Abstract

A feature recognition system and a method for identifying features of human tissue. This may use the diffraction of coherent or partially coherent light that is reflected or transmitted from the tissue. The tissue is illuminated with light from a source of substantially coherent light. A diffraction pattern image produced by reflection of the substantially coherent light from the tissue is captured by an image sensor. The captured diffraction pattern image is analysed to search for at least one pattern.
