Missile light operated proximity detector - has laser diode source associated with rapid switching logic amplifier and electrically fired fuse

摘要

The light source (12) which can emit short duration and high frequency light impulses, forms part of a proximity detection system for a missile. This is normally a laser diode and a rapid switching circuit (13). A photo detector with a photo diode (14) receiving light via a filter (15) stops much of the light from the source (12). The sequence is controlled by a timer (16) and gives signals via a gate (18). These signals are fed to a switching circuit (20) on the output (21) of a slit and to a counter (23) joined to a logic amplifier (24) and a diode (25) to a high tension source and resistance (26) and thyristor (27) and a pyrotechnique fuse assembly (28).
