High-speed swing mirror-based infrared imaging system and infrared imaging method

Abstract

The present invention provides a high-speed swing mirror-based infrared imaging system and an infrared imaging method. The system comprises an infrared lens, a swing lens, a staring type infrared area array, a video processing and display system, a motor drive system and a control terminal. The infrared lens is fixedly arranged in front of the swing lens. The staring type infrared area array is fixedly arranged at the back of the swing lens. The output end of the staring type infrared area array is connected with the input end of the video processing and display system. One end of the control terminal is connected with the video processing and display system. The other end of the control terminal is connected with the motor drive system. The output end of the motor drive system is connected with the swing lens and is used for controlling the scanning motion of the swing lens. Based on the above system and the above method, multiple targets can be tracked remotely and quickly. Meanwhile, by means of the high-precision motor drive system, the dual-closed loop feedback control of a motor can be realized. Furthermore, the rotation of the swing lens can be controlled at a high precision and a high speed, and a prosecution target can be searched.

Description

technical field [0001] The invention belongs to the technical field of infrared imaging, and in particular relates to an infrared imaging system and an infrared imaging method based on a high-speed swing mirror. Background technique [0002] At present, most security fields use non-imaging monitoring systems to monitor monitoring areas. Among them, non-imaging monitoring methods mainly include optical fiber vibration sensing monitoring methods, infrared beam-to-beam monitoring methods, and passive infrared intrusion monitoring methods. [0003] The characteristics of the above-mentioned various monitoring methods are: (1) Optical fiber vibration sensing monitoring method: This monitoring method can monitor people or things that break into the security area from other areas with high precision and quickly, and, because the light wave is in the optical fiber Medium propagation loss is small, therefore, it can be armed over a long distance. (2) Infrared cross-beam monitoring m...

Problems solved by technology

[0004] However, the above-mentioned types of non-imaging monitoring systems all use a specific trigger method to warn, so for some objects that do not need to be monitored, an alarm signal will also be generated when the trigger condition is met; therefore, it has limited monitoring accuracy and The problem of weak monitoring, especially at night, when a false alarm occurs, it will bring a lot of trouble to the security personnel, and even cause major economic losses
