Micro-lens set capable of realizing light field replication and transformation operation

Abstract

The invention discloses a micro-lens set capable of realizing light field replication and transformation operation. The micro-lens set comprises a prism, a prism group, a prism strip A and a prism strip B, wherein the long side surfaces of the two prisms are attached to form a prism group, the plurality of prism groups are connected end to end to form a prism strip A, prism strips B are arranged on the two sides of the prism strip A, the plurality of prism strips A and the prism strips B are arranged at intervals to form a micro lens set, and a light field can be copied by adopting a prism array; the smaller the distance between the prisms is, the better the copying effect of the light field is; various materials can be adopted for processing, so that the universality is better; and by adopting integral forming, the processing cost can be reduced, and meanwhile, the yield is improved.

Description

technical field [0001] The invention relates to the field of optics-related technologies, in particular to a set of microlenses capable of implementing light field replication and transformation operations. Background technique [0002] The micro-channel matrix optical waveguide flat plate produced by the Japanese inventor Makoto Otsubo is also called the equivalent negative refractive index flat plate lens. Their core is actually a plurality of vertically intersecting arrays of tiny mirrors. They use this array to replicate the light field. , can only replicate the light field to the other side of the tiny mirror at the same distance. [0003] The problem with the existing technology is that it is extremely difficult to process a tiny mirror array. First, a tiny grid plate or prism array must be processed, then coated, then cast in one piece, and finally the unnecessary mirrors must be ground. Parts, or stacked with reflectors and cut into strip arrays, the overall manufac...

Problems solved by technology

[0003] The problem with the existing technology is that to realize the tiny reflector array, its processing difficulty is extremely high. Firstly, a tiny grid plate or prism array must be processed, then coated, then integrated pouring, and finally the unnecessary Parts, or stacked with reflectors and cut into strip arrays, the overall manufacturing process is very troublesome. They are called lenses, but they should be called tiny reflector groups. This is a shortcoming in processing.

The shortcomings of their imaging can be deduced from the shortcomings of proc...
