Computer simulation of the interferometer combining properties of low-sensitive Talbot interferometer and high-sensitive holographic interferometer is considered. The interferometer has four output channels having different sensibility. Channel sensibility can be varied by means of space filtration. Wide range of the interferometer sensibility allows using the interferometer for investigation of complex phase objects. The base of the interferometer is the holographic Talbot effect found by authors.
The basic object of the computer simulation is to find the method of decoding of complex interferometric patterns produced by the interferometer. Some results of the computer simulation are presented in report. The obtained results were compared with results obtained in optical experiments under the same conditions.
The interferometer combining the best characteristics of the Talbot interferometer and holographic one is considered by this paper. The base of the interferometer is the holographic Talbot effect. As distinct from the ordinary Talbot interferometer holographic one uses instead of a second grating a photographic plate. The object is a combination of the grating and the initial phase object. The hologram is reconstructed simultaneously by the wave passed through a distorted phase object and reference wave. Four waves appear behind the hologram. This scheme may be considered as an interferometer having four output channels with different sensibility. The scheme of the Talbot holographic interferometer was simulated on a computer. The model allowed to research in detail the interferometer operation under different conditions of the hologram recording and with different phase objects.
