I think this is "Charge-Coupled Device"?
"an electronic sensor that converts light to digital signals through charges generated by bouncing photons on a thin silicon wafer"
Is that correct? Not familiar with the acronym.
- hajola 2y agoYes that's correct.
- UltraSane 2y agoYes. In telescopes they use high-end CCDs with really big pixels for better light sensitivity and zero dead pixels. This is a picture of the CCD array for the Gaia space observatory that used parallax to measure precise distances and slightly less precise angular velocities of billions of objects http://www.bo.astro.it/~altavilla/FTP/GAIA/IMAGES/The%20complete%20Gaia%20CCD%20array%20(flight%20model).jpg http://www.bo.astro.it/~altavilla/FTP/GAIA/IMAGES/The%20comp...
