Abstract

In this paper it is shown, that for modulation of path difference it is useful to use symmetrical sawtooth dependence of path difference in time of order about a wavelength of an optical spectrum. The realization of such temporary dependence is carried out with the help of piesoceramics and generator of symmetrical sawtooth impulses. The use of symmetrical impulse essentially simplifies technical realization of phase modulation in a comparison with asymmetric impulse, which was used earlier. It is shown, that the greatest value of a resonance amplification is received when the amplitude of phase modification of path difference is multiple wavelength.
