Miniature photoelectric passive distance measuring device

Abstract

The invention discloses a miniature photoelectric passive distance measuring device, which comprises an optical receiving telescope, a row of half transparent and half reflecting mirrors, a first row of imaging sensors, a reflector group, a second row of imaging sensors, and an information processing unit, wherein the first half transparent and half reflecting mirror is located on the optical path of the optical receiving telescope, receives signals of the telescope and transmits and reflects the signals; the second half transparent and half reflecting mirror receives reflection signals of the first half transparent and half reflecting mirror; and each of the rest half transparent and half reflecting mirror receives transmission signals of the former half transparent and half reflecting mirror sequentially, the received signals are transmitted and then reflected, and multiple optical paths are formed; the first imaging sensor receives transmission signals of the first half transparent and half reflecting mirror; each of the rest imaging sensors is located on the reflection optical path of the (odd number)th half transparent and half reflecting mirror; the reflector group receives reflection signals of the (even number)th half transparent and half reflecting mirror; the second row of imaging sensors receives reflection signals of each reflector group; and the information processing unit receives video signals of multiple optical paths of the first row of imaging sensors and the second row of imaging sensors, and distance inversion algorithm processing is carried out on the received video signals.

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...
