Webphotocathode, an element of a photoelectric cell (q.v.) that emits electrons when struck by light, making possible the flow of electric current through the device. A substance often used for photocathodes is a partially oxidized silver–cesium alloy. WebThe high speed shutter: a crucial feature of high speed ICCD cameras. The high speed shutter of an ICCD camera is not a separate, operational system component but an operation mode of the image intensifiers photocathode, called gating.. The open and closed state of the high speed shutter is achieved by reversing the applied photocathode voltage.
