LASER ARTICLE TARGET DETECTION SENSOR Russian patent published in 2025 - IPC F42C13/02 

FIELD: weapons.

SUBSTANCE: invention relates to weapons and can be used in proximity fuses using laser radiation for target detection. A laser target detection sensor comprising a housing, an electronic unit and receiving-emitting channels containing pulsed optical radiation sources and photodetectors connected to an electronic unit which implements time – pulse method of analysing the distance to the target, the optical axes of the photodetectors make an angle β in range from 88° to 90° with longitudinal axis of article, and receiving-emitting channels are arranged around longitudinal axis of article, wherein the pulsed optical radiation source comprises three pulsed laser diodes, the planes of the radiation patterns of the two pulsed laser diodes make an angle β in range from 88° to 90° with longitudinal axis of article, plane of the radiation pattern of the third laser diode passes through the longitudinal axis of the article and the bisector of the angle between the axes of radiation of the other two pulsed laser diodes, the photodetector comprises at least two photodiodes with filters, optical axes of which make an angle in range from 0 to 5° with bisector of angle between axes of radiation of two pulsed laser diodes.

EFFECT: higher efficiency.
