FIELD: engineering of devices for detecting optical-electronic objects, possible use, in particular, for improving informational safety of service rooms of organizations, company offices and bank institutions.
SUBSTANCE: device has emitting and receiving channels. Emitting channel has optical radiation emitter, lens and reflecting prism. Receiving channel in accordance to first variant includes objective, or an optical component, objective and photo-receiving device. Optical prism is glued to internal surface of objective or optical component of receiving channel. Optical axes of emitting channel and objective of receiving channel cross on reflective surface of prism at angle similar to it and are positioned in the plane, perpendicular to aforementioned reflecting surface of prism.
EFFECT: possible detection of miniature optical-electronic objects, for example, systems for concealed video observation (video recording), hidden in details of interior, rooms, clothing, private possessions.
