Abstract
Optical combination lock is a combination of mechanical combination lock and MEMS technology, which can effectively reduce the size of the combination lock. The mechanism of MEMS optical combination lock and code discriminator, expounds its working principle and structural characteristics, and proposes and verifies the manufacturing process of a set of MEMS optical combination lock discriminator. It not only guarantees the reliability and validity of password transmission, but also has the advantages of easy realization of password diversity and small structure size.
