Abstract

In optical information processing systems with partial and even completely of destroyed space coherence radiation, the technique of transformation of space coherence degree appears rather effective for want of creation reliable devices, capable to work in real time scale. It is represented perspective for want of to development of functional of optical information processing systems, including stages of pick up, transfer, storage, imaging to use as a main principle of construction a light field creation method with specific coherent properties. The outcomes of researches of possibility of optical sensor are resulted, in which as a disturbance value criterion the qualitative measurements of coherent properties of radiation in correlation with changes in geometrical parameters of the system is considered. The otpical system is created which can be considered as the fiber-optical sensor of mechanical disturbances of a vibrational type. The adjustable sensitivity of registration is achieved when the redistribution of a destruction level of light space coherence in an input of the system and a site of transfer of light signal. Is shown, that relative accuracy are 10^-3. The developed approach to creation of measuring system based on transformation, visualization and measurement of light space coherence changed in the communication line with natural or artificially created nonstability can find application for want of construction of location optical systems, altimeters working in actual conditions, and also for measurement system for oscillating disperse surfaces.
