Title: Radiant energy pulse detector
Abstract:
Pulse detection apparatus for optical signal pulses including ultra-violet and infra-red frequencies. A photoconductive detector cell has four ohmic output electrode terminals disposed in a rhombic pattern and a centrally disposed input electrode terminal coupled to a source of direct current bias signal. Each pair of oppositely disposed output terminals defines an axis orthogonal to that defined by the other pair. Each pair of output terminals is coupled to a signal translation device such as a transformer with a center tapped primary or a differential amplifier. A pair of output signals are produced indicative of the degree of unbalance of the cell due to an optical signal impinged thereon.
