Abstract: An optical method and system for in vivo, non-invasive imaging of biological tissue includes a stimulator and a spectrophotometer. The stimulator is constructed and arranged to stimulate cognition in a subject. The spectrophotometer is co-operatively arranged with the stimulator. The spectrophotometer is coupled to an optical module constructed to provide a multiplicity of arrayed source-detector pairs constructed for direct engagement with the subject. The system includes a light source constructed to introduce electromagnetic radiation of a visible or infra-red wavelength into biological tissue and a light detector constructed to detect optical radiation that has migrated in the tissue.

Abstract: An optical system for in vivo, non-invasive imaging of tissue change including an optical module, a spectrophotometer, and a processor. The optical module includes an array of input ports and detection ports located in a selected geometrical pattern to provide a multiplicity of arrayed source-detector pairs engaged directly with the subject. The spectrophotometer includes at least one light source constructed to introduce electromagnetic radiation of visible or infra-red wavelength into the examined tissue successively at the input ports, wherein the wavelength is sensitive to a constituent of the imaged tissue, and at least one detector constructed to detect, at the detection ports, radiation of the selected wavelength that has migrated in the tissue from respective input ports.
