ABSTRACT:
A photon emitting high speed event detector provides for the optimum detection and location of high speed events such as strobe light sources, pulsed laser, gunfire, and lightning. The detector includes a focal plane array, a control circuit and a cueing sensor. The focal plane array is capable of receiving and storing photons which are emitted from a device. The focal plane array is continuously switched by the control circuit between an integrate (charging) and non-integrate (clearing) state until a high speed event is detected by the cueing sensor. During the charging state, incident photon energy is stored by the focal plane array. Upon detection of an event, the cueing sensor instructs the control circuit to hold the focal plane array in the integrate state and the control circuit reads out the stored charge which can be provided to a video monitor for display.
