Problems solved by technology

Second, it has more advantages in the manufacturing process. The traditional large-aperture optical system is very complicated and expensive to manufacture. The lenses of some well-known telescope systems even use years as a cycle, while the microlens saves a lot of time and only needs a few days. It will be ready in a week

Abstract

The invention relates to an ultra-short-distance micro lens array interference 3D imaging mobile phone lens, which comprises a CMOS lens and an optical system located in front of the CMOS lens, and ischaracterized in that the optical system comprises three micro lenses, an optical device A, an optical device B and an optical device C which are sequentially arranged in parallel. Compared with traditional optical imaging, the technical scheme has the advantages that the volume mass is more advantageous, the mass of the camera can be reduced by 90%, the shape arrangement is more flexible, and compared with a traditional cylinder structure, the camera is easier to arrange; and secondly, the manufacturing process has more advantages, the manufacturing period is short, and the production efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the field of imaging technology devices, in particular to an ultra-short-distance microlens array interference 3D imaging mobile phone lens. Background technique [0002] The traditional optical imaging technology is similar to seeing things with the human eye, through a series of lenses or mirrors, the light from the object side is imaged on the CCD, and then the photoelectric conversion is carried out by the CCD to obtain the image. The microlens interference optical imaging technology is different. It collects light into a photonic integrated circuit through a microlens array, performs imaging in the frequency domain, and then inverse Fourier transforms it to obtain the original image. [0003] This microlens array interference imaging technology is also very impressive in terms of imaging capabilities. For a camera with a height of 500nm, a height of 300km, and a baseline length of 0.5m, the spatial resolution can reach 0.3...
