Abstract

A remote displacement measurement system based on a position sensor comprises a telescoping part and a signal processing part, an objective lens set and an eye lens set form an optical axis along the focal length of a lens, a first block prism, a second block prism, a laser transmitter and a PSD displacement sensor are further included, and the incident plane of the first block prism is perpendicular to that of the second block prism. The first transmission face and the second transmission face of the first block prism are coaxial with the incident plane and the fixed plane of the second block prism, and the incident plane of the second block prism is opposite to the second transmission face of the first block prism. The first transmission face and the second transmission face of the second block prism are coaxial with the optical axis, the first transmission face of the second block prism faces the objective lens set, the laser axis of the laser transmitter is coaxial with the incident plane of the first block prism, and the light receiving face of the PSD displacement sensor is opposite to the first transmission face of the first block prism. Measurement precision is greatly improved, and feedback signals are not prone to being influenced by environmental factors.

Description

technical field [0001] The invention relates to a signal measurement system, in particular to a measurement system for long-distance displacement signals. Background technique [0002] Aiming and collimation operation is a key action in the process of rocket launch. Its purpose is to adjust the normal direction of the prism on the platform of the arrow to the shooting direction by means of photoelectric self-collimation before the rocket launch, so as to ensure the initial orientation accuracy of the rocket, so that The rocket is in the exact take-off orientation prior to launch. [0003] Generally, by installing photoelectric transmitting and receiving components on the body of the collimator, the collimating light source uses a red light diode, and the receiving device uses a photosensitive triode. The aiming signal amplifier amplifies the received photoelectric signal, and finally indicates the deflection direction and size of the platform prism in the form of a pointer ...
