Research on the Application of Calibration Technology of Fixed-pitch Pyramid Prism Length Standard
In this paper,the calibration of the length standard of fixed-distance pyramid prism is studied.The structure of the device is described first,and then a scheme of direct aiming and rapid adjustment of optical vertices is proposed,which is used in conjunction with the laser interference length measuring device.According to the research results,the device can realize the rapid aiming and positioning of the optical vertex and center,which makes the pyramid length standard more accurate and reliable,completes the aiming and calibration quickly and accurately,and the results are accurate and reliable.
