Embodiment Construction
[0039] The present invention will be further described below in conjunction with the accompanying drawings.
[0040] like figure 1 , 5 Shown in are respectively the schematic diagram of the embodiment of the present invention and the implementation diagram of the optical path, 1 is the lens of a commercial camera, 2 is a linear polarizer, 3 is a quarter wave plate, 4 is an objective lens, 5 is a metalens array, 6 is a monochrome camera, and 7 is the target scene with depth. The structure of the superachromatic metalens array arranged in sequence in the optical path: linear polarizer 2, quarter wave plate 3 and objective lens 4, superachromatic metalens array 5, second linear polarizer 7, second four One-third of the structure of the wave plate 8 and the second objective lens 9; the scene with depth refers to the scene with different depths and staggered lateral positions in the example figure 1 For the A TEM letters in the image, letters of different colors reflect light of...
