A device in a camera that takes the light falling onto it and converts it into an electrical signal
A CCD is a semiconductor device which converts light (including X-rays) into electrical charges. The charges are then read out using a complex arrangement of electrodes, which also divides the CCD into many small, discrete areas (we call these "pixels" - or picture elements).
a bar code scanner which senses the light and dark areas of a symbol
High-resolution solid state imaging device used predominant for scientific imaging. CCDs are fabricated from silicon and designed to operate in the visible wavelengths. The CCD cameras used at the SOR are designed to be very high speed and low noise. They are used in all AO imaging aspects, including tracking and acquisition, scoring, and as focal plane arrays for the wavefront sensors.
A type of solid-state silicon wafer designed to detect light.
A semiconductor device, often used for sensing light, which operates by storing charge on capacitors and selectively moving that charge through the device by manipulating voltages on its electrodes.
One of the two main types of image sensing device used in cameras. It operates bu converting the light energy into electrical charges.
A very sensitive electronic device used in astrophotography. For further details see the article in Aries on line.
(CCD): A highly sensitive camera, this counts individual photons of light to put together an image. It can take very detailed photographs of small areas.
