Abstract

Although the Doppler-effect is well known, some recent publications discuss the necessity of relativistic corrections in the measurements of two-beam interferometers. This is remarkable because sensor and detector are in the same reference frame and, therefore, it is not necessary to employ the Lorentz transformation. The whole consideration can be made in one inertial frame even if one reflector is moving in respect to the frame of source and detector. However, the commonly used equation for the Doppler-effect for a reflection at a moving surface is not correct because this equation is derived as a quasi-static solution by using optical path lengths. If the speed of light is considered as finite a different equation containing effects of wave propagation follows. Retardation effects in interferometers are discussed in this paper and its influences to laser-Doppler measurements are derived.
