Introduction to Solid State Image Sensors

A photoelectric sensor that uses solid-state image sensing devices to convert two-dimensional images into electrical signals. Solid-state image sensing devices are highly integrated (i.e., solid-state) semiconductor photodetector arrays. Since the 1970s, with the development of silicon semiconductor technology and integrated circuit techniques, it has become possible to fabricate uniformly characterized semiconductor junctions on large silicon substrates with very high integration densities. This has created conditions for manufacturing solid-state image sensing devices, thereby rapidly advancing solid-state image sensors. Compared to traditional camera tubes (electro-vacuum devices), solid-state image sensors have advantages such as small size, low cost, low operating voltage, long life, stable performance, and no domain distortion at the edges of images.
