Abstract
AbstractAiming at the problem of preparing high-resolution compound eye, this paper proposes a multi-focal length meniscus compound eye based on MEMS negative pressure molding technology. The aperture is increased while the large field angle of view of 101.14° is obtained, and the ommatidia radius of each stage is gradually increased from 250 µm to 440 µm. A meniscus structure is used to improve the imaging quality of the marginal compound eye, so that the resolution of the compound eye can reach 36.00 lp/mm. The prepared microlenses have a uniform shape and a smooth surface, and we realize panoramic image stitching and moving object tracking. The related technologies have great application potential in the fields of automatic driving, machine vision, medical endoscopy, etc.
