Abstract

The present application provides an ICMOS-based adaptive multi-mode ultraviolet imaging detection system, including an image intensifier, a CMOS image sensor, an FPGA and a host computer; the light signal passes through the image intensifier to form an optical image, which is collected by the CMOS image sensor and sent to the host computer via the FPGA; the working process of the system includes: judging the brightness of the current detection environment, when the detection environment brightness is strong, using the CMOS image sensor to directly image; when the detection environment brightness is weak, the CMOS image sensor processes the image and performs photon counting imaging. The advantages of the present application are: through the adaptive multi-mode imaging method, the system can automatically adjust the imaging mode according to different light intensity environments to achieve real-time and efficient detection of ultraviolet signals; the system integrates FPGA as the control core, which can realize automatic control and real-time data processing, and improve the stability and reliability of the system.
