We present an interferometer based on a dynamic reflective hologram in sillenite-type crystals. A reflective pellicle was used as one of the interferometer's mirrors. The pellicle was illuminated by amplitude-modulated light to produce mechanical periodical displacements, which were detected by the interferometer. We were able to detect modulations of the light intensity within a frequency range of 0,5 Hz - 30 kHz. The mimimum measurable modulation of the light intensity was about 1-2 mW/mm², which corresponds to displacements of several 10 pm. No dependence on the wavelength in the band of 405 nm - 1550 nm was observed.
