An investigation has been made on the effects of the collimation and oblique incidence of light on the interference fringes, in applying the corner-cube interferometer for measurement of length by the method of fringe counting. It is found that the visibility of interference fringes is affected by the lateral and longitudinal shift of the moving corner-cube prism, and when the direction of incident beams on the interferometer is not parallel to the direction of longitudinal shift of the moving prism, the measured lengths have the error which is function of both shift and the angle between these directions.
