FIELD: medical equipment. SUBSTANCE: device has basic units control device, contiguous radiation spectrum radiation source, monochromatic radiation spectrum radiation source, two light guides for transmitting illuminating flows, which guides are conjugated optically with corresponding radiation sources, light guide using for transmitting image of tested surface of tissue, and beam splitter. Input of beam splitter is conjugated optically with light guide for transmitting image. The first input of beam splitter is conjugated with visualization channel which is formed by TV camera and TV display. The second output of beam splitter is conjugated with input of electro-optical unit of spectrum analyzer. Device also has analog-to-digital conversion unit and unit for conjugating with computer and computer with display. Optical-electric unit of spectrum analyzer has scanning unit mounted onto optical axis of corresponding output of beam splitter. The scanning unit is capable of sweeping image along single coordinate. There is spectral dispersing unit connected with beam splitter. Slot diaphragm is mounted at input of the unit at image plane. Diaphragm is directed in perpendicular to scanning coordinate. Array photoelectric converter is mounted at the output of dispersing unit, which has output connected with input of analog-to-digital conversion and computer conjugation unit. EFFECT: improved precision of diagnosing at early stage. |
