Basic principles of image sensors

These photographs were taken after complete disassembly (including glass shield) of an interline transfer color sensor (Sony) and a frame transfer sensor (Kodak). The photographs were taken with a binocular loupe and an optical microscope both equipped with a system of image acquisition. Other images were also taken with a Scanning Electron Microscope, but the presence of some varnish or glass film of protection did not allow to go deeper into the sensors... We present them as purely illustrative.
