Opto-electronic measuring apparatus, particularly for a projectile detonator

摘要

An opto-electronic measuring apparatus, in particular for a projectile detonator, for the delivery of a signal upon the reaching of a predetermined distance between a moving body and a surface, whereby the measuring apparatus incorporates a transmitter emitting impulses which are rendered optical through a lens at a transmission frequency; and a receiver with a receiver-amplifier for receiving the portion of these optical impulses which are scattered back from the surface.
