Optical system capable of improving adaptability of aiming device to offset target prism

Abstract

The invention relates to the technical field of collimation control, and provides an optical system capable of improving adaptability of an aiming device to an offset target prism. The main aiming device is a photoelectric collimator, the mainly related optical system of the photoelectric collimator comprises a telescope system, a luminescent system, a beam splitter prism and a cross shaft, the telescope system and the luminescent system are perpendicular with each other and achieve follow-up together with the cross shaft, the luminescent system is internally provided with a beam shaping lens group and a reticle, and a light source passes through the beam shaping lens group, is focused on the reticle and then enters the target prism through the beam splitter prism and the telescope system. According to the optical system capable of improving the adaptability of the aiming device to the offset target prism, by means of optimization design on semiconductor laser light source shaping and a follow-up mechanism assembly, the requirements that on the condition that the target prism has up-and-down offset of + / -25 mm and left-and-right offset of + / - 30 mm relative to a luminescent system outgoing light spot, collimation zero offset is not larger than 10 inches, and the collimation measurement precision meets 15 inches are met.

Description

technical field [0001] The invention relates to the technical field of automatic collimation control, in particular to an optical system for improving the adaptability of an aiming device to an off-target prism. Background technique [0002] The aiming optical system is mainly used in the strategic weapon aiming system, among which the photoelectric collimator is one of the important equipment in the ground aiming equipment. Collimation control is an automatic control system, including power amplification and feedback system, so that the value of the output variable responds to the value of the input variable. After the numerical control device sends out the command pulse, when the command value is sent to the position comparison circuit, if the pop-up The target prism on the platform does not move, that is, there is no position feedback signal. When the target prism shakes, the position signal is fed back, the servo drive motor rotates according to the command, and the uppe...

Problems solved by technology

Since the target prism of the previous model photoelectric collimator is aimed at the target prism in the centered alignment state for photoelectric collimation measurement, the light source power of the photoelectric collimator system light-emitting system only requires stability, but when the photoelectric collimator transmits the initial azimuth angle of the earth When the target prism is shot, the target prism will swing up and down, left and right within a certain range with the strong wind environment. Because the position of the system’s outgoing light spot on the target prism changes, the energy of the returned light will change. This is for the photoelectric collimator. For CCD cameras, which are energy-sensitive, and whose data processing uses the energy center of gravity method to calculate the receiving device, it will cause deviations in the collimation zero position and reduce the accuracy of collimation measurement.
