Problems solved by technology
[0003] Airborne optoelectronic pods have related optical systems in the laser, infrared and visible light bands. If an independent optical path is used for each band, it will not only bring about the problem of large volume and weight, but also cause structural deformation in the thermal environment. different, resulting in the difficulty of parallelism installation and adjustment, so a common optical path solution is required
[0004] The photoelectric pod system currently equipped cannot integrate laser communication, laser ranging, medium wave Infrared multispectral imaging and laser pressing are integrated through a common optical path

The invention discloses a photoelectric pod multi-sensor common optical path system. Based on factors such as weight reduction, integration, strong laser, weak signal and spatial axis system, the laser beam of a high-power laser is combined with the medium-wave infrared multi-spectral imaging, laser communication and ranging optical path, since the laser communication and ranging work in a time-sharing manner, the two may be placed in the same position, the structure reduces the optical path, therefore, the volume and weight of the system are greatly reduced, the difficulty of installation andadjustment is reduced, the alarm and discovery of a long-distance target by the multi-spectral imaging system are realized to obtain the distance information by laser ranging, the laser communicationis achieved, and the target may be interfered, glared and damaged.
Description
technical field [0001] The invention relates to the technical field of optical engineering, in particular to a photoelectric pod multi-sensor common optical path system. Background technique [0002] In order to realize the weaponization of airborne optoelectronic pods, it is of great research significance to design an airborne optoelectronic pod that integrates perception, detection, communication and suppression. [0003] Airborne optoelectronic pods have related optical systems in the laser, infrared and visible light bands. If an independent optical path is used for each band, it will not only bring about the problem of large volume and weight, but also cause structural deformation in the thermal environment. different, resulting in the difficulty of parallelism installation and adjustment, so a common optical path solution is required. [0004] The photoelectric pod system currently equipped cannot integrate laser communication, laser ranging, medium wave Infrared mul...
