| Abstract: | This paper presents the method of laser interference measure small angles with opticsmultiplication non-reference angles. The formula is derived for laser interference mea-sure of angles with non-reference angles and method concened. The plan is formulated,which accomplish the laser interference measure of small angles with optics, machinary,electricity and micro computer, therefore a system of laser interference measure of smallangles is built, including small angles turning terrace, optic grating system of measuringinterference pattern and microcomputer automatic handling system. Results for the methodare found to be closed to the experimental data. The repeatability error of measuringangles is less than 0.03 sec. |
