Apparatus for irradiating human tissue using multi-wavelength IR light

Anordnung zur Durchstrahlung von menschlichem Gewebe

Abstract

An apparatus for irradiating human tissue uses differing wavelengths in the IR spectrum ie. 600 to 1100 nm and ensures that the wavelengths chosen differ by at least 150 nm. The light energy is partially absorbed and undergoes scattering in passing through the tissue as a result of which the characteristic distribution patterns generated by different illumination spectra are registered by a CCD camera (1, 2, 3) for presentation as video images (4). Various devices for optimising the ergonomic design of the sensor equipment (7) are shown and algorithmic processing (8) of the recorded data (5) is used to reveal changes in tissue structure or metabolism.
