Abstract
An advanced optical sensor for determining the stand-off distance from a trajecting container to a target utilizes various checks and filters to eliminate false detonations caused by glint and counter-measures. The sensor is comprised of a transmitter, a receiver, and a wave generator. The wave generator generates a unique wave form which is relayed to both the receiver and the transmitter. The light emitted from the transmitted follows a pattern defined by the wave generator. When light is received by the receiver, a synchronous detector coupled to the wave form generator determines if the return light has a pattern correlating with the unique wave form from the wave generator. If so, the associated electric signal in the receiver must pass a predetermined threshold for a predetermined period of time before the sensor will generate a detonate signal.
