Problems solved by technology
[0005] In order to solve the refraction structure of traditional underwater cameras, the window glass is located at the front of the camera optical system. There is an interface between air and water in the system, and high-intensity pressure will be generated at the interface, which will limit the camera’s caliber. The high-intensity pressure makes the camera unable to For the problem of using in deep sea environment, the present invention provides a kind of total reflection underwater camera suitable for deep sea environment

The invention provides a total reflection type underwater camera suitable for a deep sea environment. The camera comprises window glass, a detector shell, a detector and a reflective optical system, wherein a light through hole is formed in one end of the detector shell, the other end of the detector shell is closed, and the window glass and the detector are sequentially arranged in the detector shell in the light incident direction; the reflective optical system is positioned in front of the light through hole and is fixedly mounted on the detector shell; the reflective optical system is provided with a light inlet and at least one reflector, and the relative positions of the light inlet and at least one reflector must ensure that light beams passing through the light inlet can pass through the light through hole and the window glass in sequence after being reflected by at least one reflector and are finally received by the detector. The camera avoids the influence of high-intensity pressure difference caused by an air-water interface on the reflective optical system and can be used in the deep sea environment.
Description
technical field [0001] The invention relates to the technical field of underwater imaging, in particular to a total reflection underwater camera suitable for deep-sea environments. Background technique [0002] Deep-sea optical imaging detection is a technology that combines light, mechanics, electricity, and computing for the purpose of obtaining deep-sea image information. The deep-sea camera system is an important hardware component of the deep-sea optical imaging detection system, which directly affects the image quality. [0003] Conventional underwater cameras use a refractive optical system. The window glass is located at the front end of the system, directly facing the huge pressure difference between the deep-sea seawater and the air interface, which greatly restricts the size of the window glass, which seriously restricts conventional underwater cameras. The clear aperture of the camera leads to low resolution of the camera. Literature 【1】--Jiang Chuanfu, Design ...
