Abstract

The invention discloses a long-distance photoelectric detection system, comprising: a laser emitting system, the laser emitting system is used to emit laser light; a primary mirror and a secondary mirror, the primary mirror and the secondary mirror are a common group of mirrors, used to receive multiple Waveband light incident; wherein, the primary mirror converges the incident light, the incident light is reflected by the secondary mirror to the reflector, and then refracted into parallel light by the convex lens to reach the beam splitter, and finally the incident light is separated by the beam splitter , reflecting the laser light to the single-photon ranging receiving system, and transmitting the infrared light to the infrared imaging system; the secondary mirror is connected with a rotating mechanism, and the rotating mechanism drives the secondary mirror to perform a deflection movement; the single-photon detector adopts The common aperture design of laser emission, reception and infrared can effectively reduce the size and weight of optical equipment. At the same time, the coaxial design of laser emission and infrared is adopted, which has a good optical axis consistency and ensures that the active laser and infrared act on the same target.

Description

Technical field [0001] The present invention relates to the field of photodetecting devices, and in particular, to a remote photodetection system. Background technique [0002] With the development of photoelectric technology, the photovoltaic equipment has been made higher requirements with the development of photoelectric technology. Infrared imaging can only provide the goal of the goal, pitch information, and when the device adds the laser ranging system, the distance information of the target can be provided. The system's miniaturization and light weight is considered while providing target multidimensional information. The foldback optical system is more compact compared to the transmissive optical system structure, which is conducive to the miniaturization and lightweight of the equipment. [0003] With the development of detection devices, the detection distance of refrigeration infrared detectors can have reached hundreds of kilometers, while traditional laser ranging sy...
