FIELD: medical equipment. ^ SUBSTANCE: diagnostic complex for measurement of medicobiological parametres of a skin and mucosas in vivo contains block of sources of primary optical radiation with different lengths of radiation waves, system of transportation of primary and secondary radiation to biological tissue and back, executed in the form of a harness of optical fibers with the branched out instrument and uniform working part, optoelectronic system of registration of the secondary optical radiation, containing photodetectors with optical filters, polychromator with a diffraction latitude and the device of the collecting and translation of data in the block of diagnostics results processing. The block of sources of radiation is supplied with the synchronizer with the built in generator of basic signals, the binary counter of impulses and the converter of a binary code in a positional one, and the optoelectronic system of registration of the secondary radiation, consisting of three photodetectors, is supplied with a differential formation block of Doppler signal. The polychromator it is supplied with the input lensed achromatic collimator, and its diffraction latitude is executed concave. The system of transportation of optical radiation is executed from 9 optical fibers, 8 of them are placed equally spaced in a working part on a circle around the central fiber. Inputs of sources of radiation are connected to the synchronizer outputs with a position code, its output of the binary code is bridged to an input of the device of data collecting and translation of optoelectronic system of registration of secondary optical radiation, sources of radiation are connected to the optical fibers placed on a circle, and one of fibers is bridged to constantly powered on source of radiation, on two interfacing to it from each side of the fiber are bridged to sources of radiation joining serially, each of fibers adjoining the last from both parties are connected to two photodetectors which exits are bridged with the differential formation block a Doppler signal, and an optical fiber, opposite to the fiber bridged to constantly included source of radiation, is bridged to the third photodetector, the central fiber is connected to the achromatic collimator of the polychromator. ^ EFFECT: invention allows increasing noise stability of a diagnostic complex and multitasking capability diagnostic system in a real time regimen. ^ 5 cl, 4 dwg |
