The device comprises a photoelectric turret (1) and a display control processing module (2); the photoelectric turret (1) adopts an avalanche diode imaging device and is used for searching or tracking a target under the control of the display control processing module (2) and sending an acquired video image and target position information to the display control processing module (2); and the display control processing module (2) is used for controlling the photoelectric turret (1) to switch between a search mode and a tracking mode, and processing and displaying the video image and the target position information acquired by the photoelectric turret (1). The searching and tracking device is simple in structure and light in weight, image motion compensation generated in the scanning direction and the platform motion can be achieved at the same time, the working mode is simplified, and the requirement for the anti-vibration capacity of the platform is lowered.

Description

technical field [0001] The invention relates to the technical field of photoelectric detection, in particular to a photoelectric search and tracking device based on an avalanche diode imaging device. Background technique [0002] Photoelectric detection equipment uses passive imaging to detect targets, and is widely used for its advantages of intuitive imaging and high resolution. However, the detection distance and detection range of photoelectric detection equipment are contradictory. If the detection distance is long, the observation range is small. "Observing through a straw" is a vivid description of this phenomenon. To solve this contradiction, a common way is to use a servo mechanism to rotate the photoelectric imaging detection device to scan the detection area. But this brings new problems, that is: during the scanning search process of the photoelectric imaging detection equipment, the generation and movement of the imaging point of the target on the photosensitiv...

AI Technical Summary

Problems solved by technology

The disadvantage is that electronic motion compensation is only applicable to charge-coupled devices (CCDs), and current area array infrared focal plane devices and complementary metal-oxide-semiconductor (CMOS) devices cannot use this technology

[0005] To sum up, limited by the application field of TDI motion compensation technology, in the photoelectric imaging detection equipment that does not use CCD technology, in order to achieve fast imaging, only the retrace step-staring motion compensation technology can be used, but this technology causes system problems. Large volume, weight, high cost, and low reliability make it difficult to achieve fast search imaging in small photodetection devices with strict size, weight, and power consumption (SWaP) requirements
