Underwater photoelectric imaging equipment

Abstract

The invention provides underwater photoelectric imaging equipment. The underwater photoelectric imaging equipment comprises a waterproof housing; an imaging assembly, a polarization modulation assembly, a spectral modulation assembly and an area array detector are installed in the waterproof housing; the front end of the waterproof housing is provided with a spherical optical window; the imaging assembly comprises a front imaging lens, a collimating mirror and an imaging mirror; and the collimating mirror is disposed at the rear part of the front imaging lens, the imaging mirror is installed at the rear part of the collimating mirror, the polarization modulation assembly is disposed between the collimating mirror and the imaging mirror, the spectral modulation assembly is disposed between the e polarization modulation assembly and the imaging mirror, and the area array detector is located at the rear part of the imaging mirror. The underwater photoelectric imaging equipment is advantageous in that the polarization modulation assembly and the spectral modulation assembly are integrated in the underwater photoelectric imaging equipment, a polarization direction and a transmission spectrum can be adjusted randomly, the underwater photoelectric imaging equipment has the advantage of the high degree of integration, and the underwater photoelectric imaging equipment can simultaneously improve an imaging distance and color fidelity of a target.

Description

technical field [0001] The invention relates to the technical field of photoelectric imaging, in particular to an underwater photoelectric imaging device. Background technique [0002] Underwater imaging has extensive and important application value in deep sea resource development, marine scientific research, underwater engineering operations, archaeology and rescue, and is being paid more and more attention by researchers from all over the world. At present, photoelectric imaging is one of the most important methods in underwater imaging detection technology, which has the advantage of high resolution. [0003] However, due to the special environment, current conventional underwater photoelectric imaging faces many problems, including: [0004] (1) The color fidelity is severely reduced; [0005] (2) The backscattering of active illumination light is serious, and the effective distance of photoelectric imaging is very limited. [0006] For the first problem above, the h...
