Abstract

The invention provides a dual-code identity recognition system and method, and the system comprises: a fluorescent identifier, which can generate different fluorescence spectra under different excitation conditions; a laser emitting device, which is used for emitting a coded laser pulse sequence to the fluorescent identifier loaded on the to-be-identified target based on the first coding information; an optical signal receiving device, which is used for receiving a plurality of groups of fluorescence spectrums generated by the fluorescence identifier under the excitation of the laser pulse sequence, and analyzing the plurality of groups of fluorescence spectrums to obtain second coding information; and an information processor, which is used for querying a preset target coding list according to the second coding information to obtain identity information of the target to be recognized. Compared with a single quantum dot fluorescence spectrum coding mode, the dual-coding mode in the scheme has the advantages that the identity coding complexity is increased, the identity recognition characteristics are enhanced, and the identity imitation difficulty is increased.

Description

technical field [0001] The present application relates to the technical field of identification, in particular to a dual-code identification system and method. Background technique [0002] At present, identification technology is widely used, and the current identification technologies mainly include radio identification, millimeter wave identification, laser identification and other technologies. Among them, the advantages of using laser recognition technology are: (a) the laser wavelength is short and the beam is narrow, which can obtain higher angular resolution and distance resolution, thereby improving the positioning accuracy of system recognition; (b) laser has a higher The ability to resist electromagnetic interference and anti-atom radiation is of great significance to the identification system that is often threatened by electromagnetic interference; (c) the laser signal transmission channel is narrow, it is not easy to be detected, and the confidentiality is good...
