Abstract

An interferometer based on multimode light-guide bundles is described in the report. The main characteristic feature of the proposed scheme is inclusion of a functionally important element - - corrector compensating for the interfering signals field distortions induced by a light-guide channel. The paper considers the proposed scheme and inclusion of a functionally important element -- a corrector compensating for the interfering signals field distortions induced by a light-guide channel. The paper considers the possibility of application of both regular and non- regular bundles equipped with corrective nozzles of various types. The possibility of exploiting the interferometer with its light-guide channels subjected to specific disturbances is examined. We have examined the feasibility of transferring both interferogram image and interfering fields apart through the bundle. Thus, it has been found out that interferometric information can be transferred easily enough with bundles 100 - 300 mm long for the specimens of cross-section 5 multiplied by 5 square mm - 10 multiplied by 10 square mm. Under the most favorable conditions of the experiment it is possible to reliably transfer the information about changes in specimens of 100 multiplied by 100 square mm through the bundles 1000 - 2000 mm long. For the hologram recording common photomaterials (photorefractive crystals and thermoplastic chamber) were used.
