The light splitting mechanism generally includes an image capturing element, a light splitting element, and photosensitive chips, where the number of the photosensitive chips is the same as the number of the light beams separated by the light splitting element. The working principle of the light splitting mechanism is as follows: the image acquisition element acquires an image and transmits the image to the light splitting element, and the light splitting element is provided with a preset light splitting treatment for an original image and then transmits each subimage to each photosensitive chip respectively; and then, the subsequent functional elements in the optical equipment superpose the color and brightness signals collected by each photosensitive chip through a fusion algorithm and then output an image with higher definition. Before assembly, all elements of the light splitting mechanism are independently arranged in a scattered manner; during installation, all the elements are installed in a packaging shell of the optical equipment according to the process requirements.
However, when light splitting is performed, it is necessary to ensure that the total deviation angle of the light rays under the minimum deviation condition is kept unchanged after the light rays pass through the prism, and angle fine adjustment needs to be performed on the prism light splitting to reduce the influence of optical factors on later-stage image acquisition data.
