Abstract

The invention relates to a photoelectric marking technology, in particular to an active photoelectric marking method for an MEMS (Micro-electromechanical Systems) infrared light supply array. The invention solves the problem that the conventional photoelectric marking technology is greatly impacted by external environment, cannot meet the requirements of all-weather work, cannot be used for invisible marking under an asymmetrical condition, is low in identifying efficiency, and is small in the range of a reflected light viewing field. The active photoelectric marking method for the MEMS infrared light supply array is achieved by adopting the following steps: a, an infrared light supply array module is manufactured; b, the radiation signals of an FPGA (Field Programmable Gata Array), used for controlling the infrared light supply array module, are simple point infrared spot signals; and c, the radiation signals of the FPGA, used for controlling the infrared light supply array module, are cyclic switching raster graphic signals. The active photoelectric marking method for the MEMS infrared light supply array, provided by the invention, is applicable to the fields of airplane falling guidance, pilotage, routing indication, bridge marking, personnel search and rescue, subaerial space wireless communication, identification and tracking of military targets, and the like.

Description

Technical field [0001] The invention relates to photoelectric identification technology, in particular to a MEMS infrared light source array active photoelectric identification method. Background technique [0002] Photoelectric marking technology is widely used in the fields of aircraft landing guidance, ship piloting, route marking, bridge marking, urban road marking, personnel search and rescue, and the identification and tracking of military targets. The existing photoelectric marking technology is mainly divided into visible light LED marking technology and passive reflective marking technology. The visible light LED marking technology is currently mainly used in the fields of aircraft landing guidance, ship piloting, and urban road markings. Its core component is the visible light LED (Light Emitting Diode, light-emitting diode) beacon light. The visible light LED beacon light is a solid-state cold light source based on a semiconductor PN junction. Its working principle is...
