INTERFEROMETRIC DEVICE (VARIANTS)

摘要

The inventive variant of interferometric devices which are used for studying the internal structure of objects by an optical coherent tomography method and which are embodied in such a way that they make it possible to control the location of a monitoring aria boundaries and to correct the deformation of the object cross-section tomographic image caused by the aberration of the optical length of a low-coherent light emission directed to an object under study, wherein said optical length is conditioned by transversal scanning. In the variants of the device, one or two controllable optical fibre scanners in various combinations thereof carry out the function of scanning the coherence window of the low-coherent light emission inside the studied object in the limits of the monitoring area, a function of controlling the location of the monitoring aria boundaries and a function of compensating the optical length aberration conditioned by the transversal scanning for the low-coherent light emission directed to the studied object.
