FIELD: medical engineering. SUBSTANCE: device has laser as radiation source, photodetector, transmitting optical fiber of diameter D and receiving optical fiber of diameter (2...3)D mounted in probe body. The optical fibers are mounted on in probe body guides symmetrically arranged relative to its axis allowing displacements and approaching of end faces to a distance L = (10÷15)D. Focusing lens is set on receiving optical fiber end. EFFECT: high accuracy of diagnosis. 1 dwg
