Abstract:
An imaging device for imaging light scattered by a tissue, comprising:a coherent light source for emitting light along a light path to a living tissue sample including a surface, a deep tissue layer and a superficial tissue layer positioned therebetween wherein said light source emits a first light emission along said light path and emits a second light emission along said light path; an optical assembly positioned within said light path for modifying a characteristic of the light passing through said optical assembly; and a detector for detecting a first light detection scattered by the superficial and the deep tissue layers along said light path which corresponds to said first light emission, and for detecting a second light detection scattered by the superficial and the deep tissue layers along said light path which corresponds to said second light emission, said detector being positioned with respect to said light source such that light emitted by said light source and reflected by said surface is not detected by the detector and, said detector conducting arithmetic manipulation of said first light detection and said second light detection scattered by said superficial tissue layer and said deep tissue layer for producing an image comprised exclusively of light scattered by said superficial tissue layer.
