Abstract

The invention discloses a photoelectric auto-collimation theodolite. The photoelectric auto-collimation theodolite comprises a laser, a polarization beam splitter, 1 / 4 slide, a beam collimating lens, a compensating lens, a focusing lens, an objective lens, a reflector, and a position detector, wherein the laser is used for emitting polarized beam, the polarized beam orderly penetrates the polarization beam splitter, the 1 / 4 slide, the beam collimating lens, the compensating lens, the focusing lens and the objective lens; after the outgoing beam through the objective lens orderly penetrates the objective lens, the focusing lens, the compensating lens, the beam collimating lens, the 1 / 4 slide, and the polarization beam splitter after being reflected through the reflector; the polarization beam splitter reflects the beam to the position detector. The photoelectric auto-collimation theodolite disclosed by the invention integrates the dual functions of the traditional electronic theodolite and the photoelectric auto-collimator, and can be used as a basic tool for direction measurement, and is provided with the misalignment angle measurement function at the same time; the realization is convenient, the structure is simple, and the higher measurement precision is obtained.

Description

technical field [0001] The invention relates to the technical field of optical detection, in particular to a photoelectric self-collimating theodolite with a common optical path. Background technique [0002] With the vigorous development of my country's aerospace industry, the installation and testing tasks of aerospace payload systems have become more arduous and complex, requiring measurement equipment to have higher precision, more portable, and more integrated functions. Traditional electronic theodolites, autocollimators and other instruments can no longer meet the requirements for efficient and high-quality completion of combined parameter measurement and complex detection tasks. Moreover, the existing autocollimator has the technical problems of insufficient detection accuracy and complex optical path structure. Contents of the invention [0003] In view of this, the object of the present invention is to propose a photoelectric self-collimating theodolite to impro...
