Abstract

A detector to be used for detecting photons from the visible to far infrared spectrum is described. The detector uses unique photocathodes called Advanced Semiconductor Emitter Technology (ASET) as its critical element for converting the detected photons to electrons which are emitted into a vacuum. The electron is multiplied by accelerations and collisions creating a signal larger than the sensor noise and thus allowing the photon to be detected. ASET is/composed of distinct detector and emitter technologies.
