Tomographic imaging method based on TIR prism steering common aperture emission

Abstract

The invention discloses a tomographic imaging method based on TIR prism steering common aperture emission, which comprises the following steps of: S1, emitting illumination laser, irradiating the illumination laser to a target through a TIR prism, and returning to obtain target imaging information; and S2, emitting illumination laser again, after returned target information is obtained, acquiring the missdistance of target imaging, and adjusting the missdistance by adjusting a fast reflecting mirror, so as to realize tracking control, imaging adjustment and the like of the target. The tomographic imaging method has the advantages that an ultra-long-distance target can be detected and imaged in an all-weather mode, stray light interference is reduced, and detection and imaging of the target in a complex environment can be achieved.

Description

technical field [0001] The invention relates to the field of laser active illumination tomography, and more specifically, to a tomography method based on TIR prism steering common aperture emission. Background technique [0002] Beam Control and Tracking and Targeting Equipment (ATP for short) is an important part of laser weapons and multi-functional laser combat vehicles. Achieve strike and destroy. The main function is to complete the functional links such as high-power laser transmission, pointing control, target recognition and tracking, active lighting, aiming and striking. [0003] Based on a variety of combat application environments, in order to achieve all-weather detection, identification and tracking of targets, especially for tracking targets at night, the frame rate of existing infrared detectors cannot meet the tracking accuracy of photoelectric tracking and aiming equipment, and visible light cameras cannot be seen at night. . Through laser active lighting...

Problems solved by technology

[0003] Based on a variety of combat application environments, in order to achieve all-weather detection, identification and tracking of targets, especially for tracking targets at night, the frame rate of existing infrared detectors cannot meet the tracking accuracy of photoelectric tracking and aiming equipment, and visible light cameras cannot be seen at night.

Through laser active lighting, continuous laser irradiation on long-distance targets will produce strong back-scattering. The existing technology has high requirements for the working environment, and it is difficult to adapt to complex environmental conditions. The imaging distance is short and stray light Disadvantages such as serious interference and large device volume
