Detector technology
CCD
The charge-coupled device, the detector that transformed optical astronomy — a silicon chip that converts light into electric charge with high efficiency and low noise, read out pixel by pixel. It replaced photographic plates and remains the standard optical detector; Rubin's camera is built from a mosaic of them.
