Annotation: We developed a 26-channel adaptive tomographic interferometer system, based on multiplexing of signals from fiber-optic sensors in one photorefractive crystals. The system is tested on the reconstruction of space distribution of lateral vibrations in elastic membrane with a range from 2 to 110 µm.
