3GP Camera

From another group:

<q>

The ground-based Large Synoptic Survey Telescope (LSST) is planned to have
a three gigapixel digital camera. Its data (several hundred MB/s) will be
available to the public.

....

Here is a URL for the LSST homepage:
http://www.lssto.org/lsst_home.shtml

</q>

I wonder what the dimensions of that sensor will be. Yow.

Probably just standard DX. And it'll have a bit of a noise issue, so it
will only go up to ISO 25.

Here is their link to a scale mode of the sensor:

Let's hope the sensor takes a better picture than the DSC-T20 they used to
take the above photo.

Got tired of waiting for the huge image to come via my dialup. Thanks,
though.

From the link you provided -

"Up to one thousand of these modules populating the 60-centimeter
diameter field of view will supply a parallel data stream."

That would make it 0.283 m^2 in area. With 3 GP, that would be
9.43e-11 m^2/pixel. A comparison would be a Canon EOS-1Ds, with a 36
mm * 24 mm sensor, total area 8.64e-4 m^2 that has 11.4e6 pixels, for
an area per pixel of 7.58e-11m^2
http://www.dpreview.com/news/0210/02...ensorsizes.asp
so maybe the 60 cm is plausible, and it seems of the same order as
the picture provided by another poster.
(The calculations above ignore the space between pixels, so they would
actually be smaller.)

Can hardly wait for it to develope a hot pixel and have some scientist think they've discovered a new sun or star......<g>
