Problems solved by technology

Although this prior art has certain advantages, there are still essential deficiencies: 1) this method comprises the fly-eye lens facing the object side and the fly-eye lens facing the image side, there are two groups of fly-eye lenses, and these two groups of fly-eye lenses will be coaxial , so the manufacturing process is complex, the photoelectric structure is complex, and the system is difficult to realize; 2) During the construction process, the opening diameter of the lens units in the fly-eye lens is required to be consistent, and the back focal length of each lens unit is required to be consistent, which limits the selection and design of the fly-eye lens and optimization, while increasing the implementation difficulty of the system, which affects the flexibility of system construction; 3) the focal plane image information is processed and obtained in this method, and the illuminance is based on the physical quantity, which affects the effect of collecting and processing images, and obtains images The amount of information is limited, which affects the flexibility of method integration and function expansion
