Abstract
In this paper, several test methods provided in this standard are analyzed, and the influence of the attenuation amount introduced in the test process on the test results of laser divergence angle is analyzed. Considering the test error introduced by attenuation, a method to eliminate this error is proposed, which provides the basis for accurate measurement of divergence angle.
