This paper describes a device for separating a laser radiation beam in the reference channel of a Fourier spectrometer into two beams, shifted in phase by π/2. This make it possible to constantly monitor the sign of the rate of change of the optical path difference. A plane-parallel glass plate tilted at a definite adjustable angle and overlapping half the laser radiation beam is mounted in one arm of the interferometer.
