Abstract

Modification of Koester's interferometer is described in this paper, which is used for calibration of gauge blocks up to 100mm in length. Higher precision was obtained by using a camera (for measurement of fringe fractions) and lasers as the source of light. The process of digitalization and processing of the interference pattern images is also described, as well as rejection of noise caused by transmission of laser beams through the optical fiber.
