[0002] The periscope optoelectronic sighting and aiming system is a comprehensive optoelectronic instrument that integrates multiple functions such as observation, ranging and aiming. It usually integrates multiple optoelectronic sensors and optical sighting and aiming systems. It has a typical vertical reflector group. By rotating the reflective mirror around the azimuth and elevation axes, the optical axis can be scanned at any spatial position to realize its optoelectronic sighting and aiming function. It is mostly used in vehicle-mounted or ship-mounted systems.

[0003] Periscope height refers to the vertical height of the prism or lens group relative to the horizontal optical axis in a periscope optical system. During the manufacturing process, factors such as part tolerance, improper assembly or uneven material properties may cause deviations between the actual periscope height and the designed value. These deviations may lead to problems such as field distortion, focus shift, uneven brightness, reduced system stability and reliability, etc. that affect product quality.
