Three-dimensional micro optical channel recognition system

Abstract

The invention provides a three-dimensional micro optical channel recognition system, comprising: optical signal receiving ports, optical signal transmission channels, isolation areas, and an optical signal processing device; the optical signal processing device at least includes pixel units for receiving optical signals; the optical signal transmission channels are light-permeable columns are distributed on the optical signal processing device; the isolation areas are distributed among the light-permeable columns and around the light-permeable columns; the optical signal receiving port acts as an upper surface of the corresponding light-permeable column; the light-permeable columns of the optical signal transmission channels are in one-to-one correspondence with the pixel units on the optical signal processing device. The three-dimensional micro optical channel recognition system achieved herein is small in structural size, has greatly optimized thickness particularly, and is easy to use in batch on portable electronic terminals. The three-dimensional micro optical channel recognition system is easy to package, the structural components are optimized significantly, and the three-dimensional micro optical channel recognition system has high reliability.

Description

technical field [0001] The invention relates to an electronic identification system, in particular to an identification system using an optical channel. Background technique [0002] With the advancement of modern technology, the importance of personal information security is becoming more and more important. The photoelectric sensor recognizer with photoelectric sensor technology as the core can perform information acquisition and processing functions on the test object, which facilitates the realization of digitization, intelligence and automation. [0003] The optical recognition sensor utilizes the principle of refraction and reflection of light. The light that hits the ridges on the surface of the object will undergo total reflection, and the reflected light will be projected onto the image sensor to form a black image, while the light that hits the valleys of the object will be absorbed. , forming a white image, so that the optical recognition sensor captures a light ...
