In this paper a method and an instrument worked out for evaluating roughness of machined surfaces are presented. The main idea of the method is to light up surface by laser beam and then to record an angular distribution of intensity of scattered light. Based on angular distribution of scattered light some parameters and characteristics of surface roughness are determined. This instrument can be used for measurements of flat and rotary surfaces. The application of the instrument is in the fields of full automatic testing, nondestructive testing and continuous process control.
