Abstract

The invention discloses a high-resolution multiband optical composite imaging detecting system and a method thereof, wherein the system comprises a front telescope module, a phase correcting and imagemotion compensating module and a sensor imaging module, wherein the front telescope module acquires an objective optical signal, compresses a light beam caliber and transmits the objective optical signal to the phase correcting and image motion compensating module. The phase correcting and image motion compensating module performs phase correction and image motion compensation on the objective optical signal after light beam caliber is compressed to the sensor imaging module. The sensor imaging module divides the optical signal after phase correction and image motion compensation to visible light and mid-infrared light, thereby realizing visible light imaging. The mid-infrared light is reconstructed for obtaining a super-resolution image through four image frames and a super-resolution algorithm. The high-resolution multiband optical composite imaging detecting system has advantages of improving infrared resolution, reducing imaging fuzzy caused by high-speed moving platform motion and system scanning. Furthermore the system and the method have advantages of low power consumption, small size and small weight.

Description

technical field [0001] The invention belongs to the technical field of target optical detection, and in particular relates to a high-resolution multi-band optical compound imaging detection system and a method thereof. Background technique [0002] Small space vehicles flying at high speed need to complete high-resolution and clear imaging of the ground and sea scenes through a multi-band optical composite detection system. However, limited by the size, weight, and power consumption of the aircraft, the optical detection system needs to be lightweight and miniaturized. Considering factors such as system capabilities and platform limitations, it is necessary to optimize the scheme design of the visible light / infrared composite imaging detection system, and adopt some new technologies to improve the resolution and suppress the imaging blur that may be caused by the platform and system. [0003] There are already some satellites at home and abroad that specialize in high-resol...
