Cross-medium imaging multifunctional optical system and control method

Abstract

The invention discloses a cross-medium imaging multifunctional optical system and a control method, the cross-medium imaging multifunctional optical system comprises a pressure-resistant protection window, a multi-channel common lens group and a beam splitter group which are sequentially arranged from an object space to an image space along a light ray direction, and the light ray is divided into two beams of light rays from the beam splitter group, the first light beam is sequentially provided with a common rear fixed lens group for underwater imaging and water surface imaging and a water surface imaging switching lens group, and the water surface imaging switching lens group can be cut in and cut out from the first light beam; and the second light beam is provided with a fixed lens group after underwater air laser detection. The beam lens group and the water surface imaging switching lens group are utilized to integrate the functions of underwater to-air imaging, underwater to-air laser detection and water surface imaging, so that the blank of underwater to-air imaging and laser detection of the underwater underwater vehicle is filled up, the detection blind area of traditional photoelectric equipment carried by the underwater underwater vehicle is made up, and the detection performance of the underwater underwater vehicle is remarkably improved.
