Реферат: An apparatus for measuring and imaging blood perfusion in tissue comprises a monochromatic laser light source, means for shaping the laser light beam, means for irradiating a section of the surface of the tissue with the laser light beam, means for collecting light scattered from the irradiated section, an image sensor comprising a plurality of photodetectors, each photodetector of the sensor being able to receive collected light from a predetermined sub area of the section of the tissue surface and produce a corresponding electrical output signal linearly related to the detected instananeous laser light intensity; means for processing the electrical output signals from the plurality of photodetctors, means for calculating the average Doppler frequency shift for each sub area from which scattered light is detected, means for producing an image of the blood perfusion in the tissue section irradiated from the processed output signals, and an image display means. The apparatus enables fast tissue blood perfusion image to sub second times.
