Abstract

The invention discloses an underwater optical imaging device with axial multi-sensors, which includes an optical system, a first image sensor and a second image sensor, wherein the optical system receives the target light beam and the target beam formed by the suspended particles after the imaging target receives light. Backscattering, the first image sensor and the second image sensor are installed on the optical axis of the optical system, receive images of different focal plane positions, and propagate between the first image sensor and the second image sensor according to the target beam and backscattering The equivalent optical point spread function of the image is differentially processed to extract the target information. The invention utilizes the difference between the back scattering and the transfer function of the imaging target in the optical system to suppress the back scattering and obtain clear underwater long-distance target images.

Description

technical field [0001] The invention relates to an underwater optical imaging device with axial multi-sensors. Background technique [0002] Backscattering is the main factor restricting the working distance of underwater optical imaging. However, due to the randomness of scattering, it is difficult to extract the optical characteristics of backscattering, and it is difficult to improve the quality of underwater optical imaging. Contents of the invention [0003] In order to solve the above problems, the present invention proposes an underwater optical imaging device with axial multi-sensors. The present invention utilizes the difference between the backscattering and the transfer function of the imaging target in the optical system to suppress the backscattering and extract effective target information. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] An underwater optical imaging device with axial ...
