Given an image under a projection, like a photograph, we can infer its so-called focal length. optics such that the size of the image of the chandelier corresponds to that of the real chandelier.
And I like to take that metaphor even further. From optics , to outcomes, to ownership-- and this is the message for the leader of the organization. And the time I was at Rideau Hall, one of the functions of the governor general is to receive the letters of credential,
It was a Canon D60. Sea and Sea Housing. But pretty much the anatomy of an underwater rig has not changed. You have some kind of housing, a very large dome port for wide angle, for the optics thatófor clear, sharp wide angle shots underwater. Some kind of lighting, so in this case, two Ico Light strobes, and articulating arms. This is a shot thatís a little bit more recent. Again, the cameras have not changed that much in the professional underwater photography world, still photography world. This is a
So there's a lot of modelling and a lot of other investigations going on to further explore this question. We've had another amazing discovery using adaptive optics just in the last year. In November 2008, this was announced. I was telling you how we now know of 400 extrasolar planets but we know about them indirectly from this -- from looking at the motions of their, of their
It's so warm and inviting-- It's so warm. Now the optics of that may not be ideal because that's a premium streaming service.
And he's published a big catalog. But with adaptive optics using laser guide stars, for example, you can improve the seeing.
But it really informed how she's set up in that moment when she's asking for that promotion. And the optics of what you choose to wear in a work environment was something we discussed across the board with all of these characters. But that was very specific, that that was the outfit that she was going to wear on that day that she was going to ask for that promotion .
It's actually still being opened as we speak. But this was the optics gallery, dark on purpose because of the phenomenon. And already you're starting to see the kind of engagement that we hope to see and ultimately the reason why we do what we do.
throughout the program. There were some optics -type thing-- and I don't mean optics the discipline. I mean optics the-- just how things look. By moving the program scientists on the org chart up next to the program manager-- the mail code for payloads
In California here maybe it would be one and a half arc second, one arc second. We can get down to resolutions of .15 arc second using adaptive optics on Keck. That's better than the resolution you get in the optical with Hubble space telescope. So we're -- we're liberated at infrared wavelengths where this works and going into red wavelengths from the expense and complexity and risk of launching telescopes above the earth's atmosphere. We can build them on earth.
It's a real problem when we're researching for our videos. I was reading up on lenses and optics , and a few days later I started getting targeted ads for glasses and eye surgery. So someone out there is probably selling my browsing data.
What happened? Well, in the year 2000, a very famous painter, David Hockney, came up with a bold and very controversial theory that some of these early artists use optics during the execution of their works. He put this forth in his book "Secret Knowledge." Here's one of his paintings at the upper right.
So it's just a marvelous time in sonics. I call sonics the new optics . I believe it's as profound a revolution as the telescope or the microscope.
agency, all of these things, we felt have their own merit and are important. the phenomenon of light and optics and transforming an environment into a work of art.
In 1947, the first demonstration in New York was just a sensation. He demonstrated his invention at an optics convention at the Hotel Pennsylvania in New York. And it got a huge story in "The New York Timess," plus an editorial that said, "there is nothing like this in the
Just to being able to do better imaging through the atmosphere period. But its absolutely revolutionary for astronomy. So we get a gain in spatial resolution using the Keck telescopes with adaptive optics on versus adaptive optics off of between 10 and 20, depending on the atmospheric conditions. Typically, on a reasonable night on Mauna Kea if we don't -- if we're not using adaptive optics the characteristic size of an image is a half an arc second. So 1/3,600th of a degree.
They can become more adaptable over their lifetime as new technologies come available. And this is all thanks to adaptive optics . So how -- what do we apply this to? Let me give you a sense of the scientific questions that are really -- been opened by adaptive optics . So the center of our galaxy is an area very
The -- just the density is a lot, is a lot higher there. But astronomers until they had adaptive optics weren't really able to study it very well. It's -- we're looking through the plane of the galaxy, the plane of the Milky Way to get to the galactic center. There's a lot of absorption by dust so we
And so for the first time in late 2008, this star, HR 8799, was imaged with Keck Observatory. And the idea is to use adaptive optics to make the image of the star as small as possible. So that you're -- so that it's -- and then try to block it out, so that you've removed the source of glare, and you can see the
So there are basically three ways to generate EUV, to build a sun on Earth. So Zeiss built a nervous system directly into the optics , robot-guided sensors that constantly measure the exact position and angle of each mirror
So there are basically three ways to generate EUV, to build a sun on Earth. While Zeiss was doing a stellar job with the optics , ASML was still struggling with the power source.
And do you get a sense that Spain learned from what happened 2 weeks ago? Has has anything substantial changed or is this really more about optics ? Well, I think we have to distinguish between the situation at the border and the situation in the rest of the city.
the corners of the eye, the tip of the nose, the corners of the mouth and so forth-- onto the picture plane. And not that it was done literally using any sort of optics or geometry or so forth, but this is just the artist's forward model. And based on the locations of these key points, we can infer the rotation angles.
Given an image under a projection, like a photograph, we can infer its so-called focal length. Well, it's basic optics of law, of reflection off of a sphere that leads to distortion of the image.
Anything that you can identify with your eye, that a clinician identifies, from endoscopic procedures to skin, you should be able to do with a mobile device. You just need to tweak it-- so using the right optics , the right illumination, the right structures, and so on. But there's so many other ways to do it.
of the classics-- the Greeks about perspective and optics -- were being reawakened as that information that were actually
We actually need to be able to use optics , the optics we provide, to be able to push beyond tier-one and understand where
They'll be helping set up some fiber optics , I guess wiring and cables to make for Wi-Fi connectivity.
And so the way this was done was through fiber optics .
It's sort of like the Caesar salad dressing of optics .
we have to deal with the remainder. So we cope with this with adaptive optics and Keck was the first large telescope to have an adaptive optic system. So this the schematic of how an adaptive optics systems works to remove the turbulence in the atmosphere which causes that kind of twinkling or shimmering of the stars. The light comes into this system, and this is a deformable mirror. It can change its shape 2,000 times a second.
the Keck telescopes with adaptive optics on versus adaptive optics off of between 10 and 20, depending on the atmospheric conditions. Typically, on a reasonable night on Mauna Kea if we don't -- if we're not using adaptive optics the characteristic size of an image is a half an arc second. So 1/3,600th of a degree. In California here maybe it would be one and a half arc second, one arc second. We can get down to resolutions of .15 arc
So play this -- take this technology and play it forward with much greater capability. This is an image of -- for our adaptive optics system with Keck.
So play this -- take this technology and play it forward with much greater capability. We want and need to be able to use adaptive optics everywhere.
- In the early days, anything between five and 14 nanometers was explored. The thing is you need to find a source and you need to find optics that reflect the wavelengths. - Right. - So you have to look for the combination.
years. The telecommunications uh fiber optics , 30 years. All of these investments were multi-decade
And he worked 700 years before Isaac Newton on the study of optics .
they were thinking about the um the you know the um diag the Optics diagrams um
And even if not just empathy-- like, understanding optics .
There are people to think that anybody who talks about any artist using optics in any way is defeating the whole idea of art,
But you're inferring from that because we're talking the language of optics .
So one of the things we did is we got rid of the separate program aspect of all the science that we're doing, disseminated those individuals throughout the program. There were some optics -type thing-- and I don't mean optics the discipline. I mean optics the-- just how things look.
understandings. And in his treatise Optics published in 1794 he criticized other scientists who were trying to
um used actually a kind of a mechanical equivalent of the Adaptive Optics uh
They want to know, they wanna discuss optics and some of the particular things about - I, I'm much more into the whole experience of it. And not until you really let go; and what
And you can see it gives a beautiful image. This is the inner one arc second of the galaxy. So it's a tiny area. Without adaptive optics , this would just be a blur. Now we always knew this was a very interesting place going way back, because one of the brightest radio sources in the galaxy is at the galactic center. But there was very little known about the
place going way back, because one of the brightest radio sources in the galaxy is at the galactic center. But there was very little known about the stars right at the very center of the galaxy until -- until adaptive optics on the Keck telescope started probing this area at very high resolution, led by Andre's group. And then I'm going to show you what the motions of these stars are like with adaptive optics , this is a cartoon. This is the year the data was taken, and it's
in our galaxy. So it's a wonderful laboratory for physics and astronomy. And we didn't even know about it, you know, before the Keck telescopes started looking at this area of the sky with adaptive optics . So it's probably the best place that we have to test the theory of general relativity and the strong gravity limit. It's a wonderful place to understand the properties
So play this -- take this technology and play it forward with much greater capability. can create an artificial beacon near any place that we want to do adaptive optics on the sky. And so I've -- this is, this is a recent technical
So play this -- take this technology and play it forward with much greater capability. Extremely committed to bringing on new technologies and new instrumentation and adaptive optics systems to allow the Observatory to do more each year and discover more.
