Due to the physiological differences of the respective condition of the skin with regard to the moisture content, the fat content of the structure and texture but also as a result of a therapeutic or cosmetic treatment, a correlation to the condition of the skin can be determined from the detected quantities.
  • the registration and data processing can be carried out both in real time (live) and off-line, so that a quantification, ie calculation of a respective factor with regard to the condition of the skin, is made possible immediately after detection and processing.
  • the arrangement for performing the method provides that both coherent (for example laser diodes, LEDs) and incoherent (for example xenon or halogen lamps) light sources can be used as light sources.
  • detectors e.g. a photodiode array, a CCD camera or a multi-channel analyzer array (MCA array) are used. Depending on the detector used, different, more extensive measurement parameter recordings and evaluations are possible.
  • the evaluation electronics receive the recorded image data as input and use this to calculate a factor of the skin.
  • an MCA array permits the spectrally and spatially resolved measurement of the reflected light beam.
