Abstract
A non-destructive testing technique, particularly suitable for the non-invasive examination of human body tissue, wherein the object of interest is transilluminated with multi-wavelength light. Apparatus for practicing the technique generates transillumination light containing different colors and the light which passes through the tissue is divided and filtered to provide plural light beams lying in separate wavelength ranges. These light beams are detected by a video system which provides information bearing signals to data processing circuitry which determines the transmissivity at each wavelength of each point of the object within the viewing field.
