1. An infrared radiation modulator comprising three parallely arranged interferometer plates made of a material having a limited absorption rate in the wavelength region of the radiation to be modulated, said interferometer plates forming two successive interferometric slits therebetween for passing the radiation to be modulated, the two outer plates of said three interferometer plates being stationary, and the central plate being suspended to a flexural resonator such that the width of said slits is periodically varied, the interferometer plates being comprised of monocrystalline doped cadmium telluride (CdTe) having a high resistivity and a limited absorption rate for infrared radiation.
