Embodiment

[0050] figure 1 A schematic diagram of the design method of a non-uniform curved surface compound eye lens of the present invention is shown.

[0051] Such as figure 1 As shown, it is an innovative design scheme of a double pumping curved surface fly eye lens. The core idea of ​​the design of the non-uniform sub-eye is to make the focal length of each sub-eye different. non-uniform arrangement to achieve. Light rays of different angles enter from the plane end of the curved surface fly-eye lens and exit from the curved surface end, which coincides with the optical axis of each sub-eye. Assuming that the central sub-eye is a first-level sub-eye, the distance from it to CMOS is l 1 , it can be defaulted that its object-space focal length f′ is equal to l 1 , extending from the first-level sub-eye to the periphery, respectively l 2 , l 3 ...l m , l m As the number of sub-eyes increases, the larger the value, the defocus problem of the curved surface fly-eye lens is solved...

Abstract

The invention provides a design and preparation method of a non-uniform curved fly-eye lens. By setting sub-eyes with different calibers and sagittal heights at each level on the curved-surface fly-eye lens, different sub-eye focal lengths at each level are obtained; The plane end of the fly eye lens is injected into and emitted from the curved surface end, and the rays of different angles pass through the optical center of the sub-eye, so that all the refraction focus of the light falls on the same plane; Eye. The lens is prepared by two air pressure assisted and ultraviolet curing processes, which is short in time, high in efficiency, good in repeatability, and uniform in surface morphology.

Description

technical field [0001] The invention is designed in the field of micro-nano processing, mainly a new design scheme and preparation method of compound eyes with non-uniform curved surfaces. Background technique [0002] In contemporary times, microlenses are currently widely used in detection and imaging systems in the fields of national defense, medicine and civilian use. With an optical imaging system composed of a single lens, it is difficult to obtain a wide field of view. Only a fisheye lens can be larger than 90°. At the same time, this traditional optical imaging system usually uses a lens group for imaging, which has a large number of lenses, a large volume, and a complex structure, making it difficult to integrate and integrate with various miniaturized systems. [0003] On the basis of the microlens array research, the researchers were inspired by the compound eyes of insects and hoped to integrate an artificial compound eye imaging system. The curved surface comp...
