| titleOfInvention | Underwater imaging lens imaging quality parameter detection method and underwater special collimator |
| abstract | The invention belongs to the field of underwater optical detection, and relates to a method for detecting imaging quality parameters of an underwater imaging lens and an underwater special collimator. Overcoming the problem that the reliability and accuracy of the detection results obtained by using the existing detection methods are difficult to guarantee. By generating parallel beams in the water, in the actual water environment, the imaging quality of the underwater imaging lens can be directly detected, and the direct measurement value can be obtained to ensure the reliability and accuracy of the measurement result. The underwater special collimator light pipe provided by the present invention includes a sealed casing and an optical component located inside the optical component; the optical component includes a lighting component, a reticle component and a collimating optical system arranged coaxially in turn along the beam propagation direction of the lighting component; The straight optical system is used to collimate the incident light beam and ensure that the light beam that exits and enters the water body is parallel light. It can not only be used to detect underwater imaging instruments, but also can be used as a standard parallel light source for the study of light transmission mechanism under water. It is the basic instrument of underwater optics. |
