Abstract

The invention provides a device and a method for coaxially adjusting double beams in real time. The device and the method realize coaxial convergence of the double beams by modulating the double beams and turning back rays, and meanwhile realize detection and real-time adjustment of the double beams by taking coaxial light split parts of the double beams as detected beams and performing light splitting treatment on the detected beams; and alternated adjustment of the double beams ensures high-precision coaxial collimation of emergent beams and overcomes the defect of the prior art on the aspect of coaxial real-time adjustment of double laser beams. The device and the method have high adjustment speed and precision, do not affect normal use of equipment during adjustment, ensure continuity and accuracy of observation and measurement, can be applied to the double beams with different wavelengths, and can detect the double beams at the same time by using a set of detection module so as to save devices with low cost.

Description

Technical field [0001] The invention relates to the field of precision or ultra-precision optical measurement, in particular to a method and device for coaxial real-time adjustment based on dual laser beams. Background technique [0002] Laser beams are widely used in various precision or ultra-precision optical observation and measurement equipment due to their good monochromaticity, directivity and high brightness. However, due to the high heat generated by the laser during the excitation process, it is easy to cause the deformation of the system components and the uneven refractive index of the air caused by the temperature and humidity changes in the operating environment. The laser beam is prone to parallel and angular deviations, which will increase over time. This phenomenon will become more serious as time goes by, greatly affecting the accuracy of precision observation and measuring equipment, and even the service life of the equipment. With the development of science a...
