Description

technical field [0001] The invention belongs to the technical field of photoelectric positioning and photoelectric countermeasures, and in particular relates to a miniaturized photoelectric passive distance measuring device. Background technique [0002] With the continuous advancement of new military technology changes, high-tech weapons such as precision guidance and fixed-point strikes emerge in an endless stream, becoming the main battlefield for various military powers. The premise of precision strike lies in high-precision target situational awareness, not only the two-dimensional intensity information of the target, but also the distance and orientation information of the target. Among them, the distance information is the basis of positioning, so in the photoelectric positioning and orientation, the most core is the photoelectric ranging technology. [0003] Photoelectric ranging technology is mainly divided into active ranging technology and passive ranging technol...

Problems solved by technology

[0005] In order to solve the problems caused by the bulky system in traditional multi-station ranging, the difficulty of coplanar imaging horizontal datum planes between multi-stations, large measurement errors between datum planes under non-coplanar conditions, and consistency errors in the measurement of target inclination angles between multi-stations, etc. To solve the problem of low accuracy of distance inversion, a miniaturized photoelectric passive ranging device is proposed. The optical path difference is formed through the reentrant optical path conversion, which can greatly reduce the volume and weight of the device, and realize coaxial imaging between multiple sensors. Improve the distance measurement accuracy, which is beneficial to the engineering application of related technologies
