In order to realize detection and precise positioning of small-caliber visual optical system targets, according to the "cat eye effect" of photoelectric system, the research based on laser active reconnaissance precision detection technology was carried out. The effects of parameters such as laser emission power, receiving aperture and detection distance on the detection performance are simulated. The experiment has verified the ability to detect small-caliber targets under certain laser power. The experimental results show that the 10mm aperture visual optical system at 700m can be accurately detected under the condition of laser peak power of 1000W and laser divergence angle of 1.5mrad.

In order to improve target recognition and accurate positioning, A Non-synchronous processing method base on distributed laser warning signal has been put forward。 First, Work principle and system constitution of distributed laser warning are introduced. The time information of receiving the alarm are exported by pulse form when laser warning device received threat warning signal, then this warning signal are processing and export warning position and other data information by the bus form. The processing center of the warning data receives time information and data information from different sensors. Finally, these not- synchronous warning information carry on fusion with synchronous processing by means of time scale and deviation value. Concrete warning position are obtained through the method and high accuracy recognition probability is achieved, which has higher engineering application value.
Designed an off-axis aspheric reflective zoom optical system, and produced a prototype. The system consists of three aspheric reflective lens, the zoom range is 30mm ~ 90mm. This system gave up the traditional structure of zoom cam, the lens moved using linear guide rail driven by motor, the positioning precision of which was 0.01mm. And introduced the design of support frames of each lens. The practice tests verified the rationality of the prototype structure design.
