Fermilab Builds 500-Megapixel Camera 180

Posted by simoniker from the quite-large dept.
heyitsme writes "Fermilab, a U.S. Department of Energy research lab, is part of a collaboration on an experiment to measure the properties of dark energy. The Dark Energy Survey would measure the history of the expansion rate of the universe more precisely than ever before, using the largest camera ever built with Charge Coupled Devices (CCD). The 500 megapixel Dark Energy Camera (DECam) would be placed on an existing 4-meter telescope located in north-central Chile at the National Optical Astronomy Observatory's Cerro Tololo Inter-American Observatory. The DECam together with the CTIO 4-meter telescope will allow for a survey of 15 percent of the sky to light levels faint enough to measure the colors of galaxies at redshift one."

      The detector actually contains roughly 503,316,480 raw pixels, this amounts to slightly less than 500,000,000 effective pixels after initial processing.

      The data will, of course, be stored directly to a large SAN storage system, probably from EMC or Hitachi.

      The detector should generate single frame images of roughly 1.7G prior to post-processing, and roughly 700M single-frame image files after processing to TIFF or PNG format.

      Although the article does say 500 megapixel, a simple calculation could answer your question. The CCD is composed of elements giving it a pixel array of 180k X 240k pixels giving us 28800000000 pixels! (Assuming each pixel holds one grey value in a 16 bit image ) Working from 16 bits/pixel and 8 bits/byte, we are looking at 2 bytes per pixel. So 2 bytes * 28800000000 pixels gives us 57600000000 bytes or almost 54 GB/image!

          So, we here in academia are a bit spoiled in terms of bandwidth. However, companies and some in academics have to pay for lots of bits and bytes and are thus interested in costs to move these sorts of data. I was talking with Jim Gray a couple of weeks ago and he was telling me that a recent study revealed some of the true costs of moving lots of data. For instance: Lets say you are trying to move a terabyte of data from London to Los Angeles. It turns out it is cheaper (and faster) to put it on magnetic storage and fly it from London to Los Angeles than it is to try and move it over the Internet.

        Interesting, the numbers you show don't appear anywhere in the article. Instead, I see:
        At the heart of the DECam are 60 rectangular (2k x 4k) CCDs, each with 8 million 15-micron pixels. The CCDs, developed at Lawrence Berkeley National Laboratory, are over five times more sensitive at near-infrared wavelengths than conventional CCDs currently used for astronomy.
        60 CCDs at 8 million pixels each for a total of only 480 million pixels. There's no mention of color filtration so grayscale is a safe assumption. There's also no mention of resolution but 16 bits sounds good as a guess.

        So 960 million bytes per frame, which is only 915.5MB (1M = 2^20).

            Chapter 4 covers the data acquisition requirements in detail. The detector is composed of 60 CCDs with the following characteristics:

      Probably not. Digital zoom is useless because it just magnifies part of the picture without increasing resolution. It may be useful for video (especially if the CCD has a higher resolution than TV) but it's essentially a "marketing feature" for still photography.

      Anyway, with 500MP you're going to be severely limited by the resolving power of the lens. It's quite difficult to get even 100 line pairs per mm with the best 35mm photographic lenses (lenses for larger formats tend to be much worse because it's harder to maintain accuracy over a large glass area, plus it's not as necessary with lower enlargement factors). A 500MP sensor needs a pretty exceptional telescope in front of it.

    (Not an expert, they're all fast asleep right now.)

    One of the things Fermilab is trying to do is get a measurement of the so called weak lensing effect. Matter distorts spacetime, and light is thus bent as it passes nearby a big cluster. This is gravitational lensing.

    Famously, it is seen as "strong" lensing -- when the source is very close on the sky to the cluster, and the light gets bent enough that there are multiple images. Nobody really believed it could happen, but then in the last decade or so it's become an accepted and popular thing to play with and observe.

    Weak lensing is when there are no multiple images, and instead only a slight distortion. Much harder to see and measure -- you basically look for a whole bunch of galaxies that are slightly distorted.

    That means you need a very wide field of view -- to get enough galaxies quickly enough -- but also a very good resolution -- to be able to measure the slight distortions. Hence the need for such an insane[ly cool] device.

    Why go through all this trouble? Well, weak lensing is one of the view ways to measure all the matter in the universe on very large scales. Because nearly all the matter is supposed to be invisible, in the past people have used various "tracers" that we can see. But there's a huge amount of debate as to how good the various tracers are, and, of course, you need a direct measurement to be sure you're not off in la-la land.

    Weak lensing measures it all because all matter, regardless of how bright it is, bends spacetime in the same fashion. So, if you can get a good weak lensing measurement, you can theoretically create an unbiased map of the matter distribution. No need to cross your fingers and hope that some tracer is behaving properly.

    It all fits into dark energy because dark energy is supposed to alter the extent to which matter can cluster (roughly speaking, dark energy behaves like antigravity, and pushes things apart, stopping them from falling together.)

    Of course, weak lensing is just one of the things this guy is meant to do -- there are lots of other neat things that hopefully someone more awake than I can describe.
    • This critter is so cool it's almost scary... I'm waiting for the astronomer to say cheese, and after accounting for weak gravitational lensing we get a picture of God smiling back!

    • Indeed, the more pixels, the smaller the pixels. And the less light they capture.

      But you should read the article : we talk about a one-halfmeter-diameter DECam , so the pixels (15-micron) arent that small as in your pocket camera ;-)

      At the heart of the DECam are 60 rectangular (2k x 4k) CCDs, each with 8 million 15-micron pixels. The CCDs, developed at Lawrence Berkeley National Laboratory, are over five times more sensitive at near-infrared wavelengths than conventional CCDs currently used for ast

    There seems to be a lot of interest all of a sudden on slashdot on super high res images (yesterday there was an article on a large film camera which was by no means revolutionary or record setting). It's really not that cutting edge. If you go to www.betterlight.com, they're releasing a 4x5 back capable of 10200x13800 pixels soon, and already have one available that's about 100 Mpixel. Granted, these are slow, but they've been available for a long time and are used daily by product photographers. I shoot 4x5 myself on film and make 550 MB scans. It's relatively cheap and very high res.

It is estimated that the vast majority of information in Universe is "dark", and most memories are nemories.
