Abstract

The present remote data monitoring system employs a laser and a modulated retroreflector for the remote data monitoring of hard to access spaces, targets etc., in combination with an arrangement for a simultaneous friend-or-foe identification, and in combination with devices for the protection against detection and against interrogation of a friend by an enemy laser. In this system, a liquid crystal modulator of special construction depending on the purpose and structure of the system, is arranged in front of a retroreflector and modulated by the respective information. The information is interrogated by a spatially distant laser station by directing a laser beam onto the retromodulator, whereby the information is retroreflected and simultaneously modulated.
