The operating principle and the error of an interferometer of which reflecting mirrors are a pair of front-surface mirrors mounted to form a right angle, were discussed analytically. It was found that when the interferometer was used for the measurements of length by the fringe countiug method, the following adjustments were most important
(1) the positions and dimensions of entrance apertures of phototubes.
(2) the linearity of the locus of the moving mirror pair and
(3) the angle between the intersection line of the moving mirror pair and the direction of incident parallel light.
