Embodiment Construction

[0031] In order to facilitate those skilled in the art to understand and implement the present invention, the present invention will be described in further detail below. It should be understood that the content described here is only for illustrating and explaining the present invention, and is not intended to limit the present invention.

[0032] like figure 1 As shown, a laser light field visualization device based on an InGaAs camera includes a two-dimensional servo turntable, a zoom lens set on the two-dimensional servo turntable, a fixed-focus lens, a first InGaAs camera, a second InGaAs camera, and a laser angle encoder. Devices, timing control modules, lasers, photodetectors, ranging circuits, beam splitters, and system control modules.

[0033] The laser angle encoder responds to the incident light of the set band, and encodes the angle of the incident light, and outputs the laser incident angle and laser incident time to the timing control module.

[0034] The targe...

Abstract

The invention discloses a laser light field visualization device based on an InGaAs camera, and the device comprises a two-dimensional servo turntable. The device further comprises a zoom lens, a prime lens, a first InGaAs camera, a second InGaAs camera, a laser angle encoder, a sequential control module, a laser, a photoelectric detector, a distance measuring circuit, a beam splitter prism and a system control module which are arranged on the two-dimensional servo turntable. The invention further discloses a laser light field visualization method based on the InGaAs cameras. Capturing and imaging of laser at an unknown emission moment are realized, and light field visualization is realized. The problem of capturing and imaging of laser beams at unknown emission moments is solved, the angle positioning resolution is high, and the visualization of a laser light field is realized.

Description

technical field [0001] The present invention relates to the field of optoelectronic countermeasure systems, more specifically to a laser light field visualization device based on an InGaAs camera, and also to a laser light field visualization method based on an InGaAs camera, which can realize the capture and imaging of laser light at unknown emission times, Realize visualization. Background technique [0002] The capture imaging of laser light field is an important content of laser warning technology and an important part of photoelectric countermeasures. On the battlefield, whoever discovers the opponent first will have the upper hand and take the initiative. Only by accurately obtaining the characteristics and orientation of the incoming laser, can we take correct defensive measures accordingly and protect our own safety at the first time. On this basis, according to the exact location of the threat source, effective countermeasures can be taken to interfere or destroy ...
