ABSTRACT:
The interferometer is fed by a laser whose wavelength is modulated. The frequency of the optical fringes generated by modulating the wavelength of the laser are measured. Preferably, the measurement of the frequency is carried out by counting pulses. A system for carrying out the method includes a pulse counter circuit.
