1. An optical system for in vivo, non-invasive imaging of tissue change comprising:

  • an optical module including an array of input ports and detection ports located in a selected geometrical pattern to provide a multiplicity of arrayed single source, single detector pairs enaged directly with the subject;

    a spectrophotometer including light source means constructed to introduce electromagnetic radiation of visible or infra-red wavelength into the examined tissue successively at said input ports, said wavelength being sensitive to a constituent of the imaged tissue;

    detector means constructed to detect, at said detection ports, radiation of said selected wavelength that has migrated in the tissue from respective input ports; and

    a processor receiving signals of said detected radiation from said detector means, and constructed and arranged to create a defined spatial image of the tissue by effectively producing from signals from the multiplicity of arrayed single source, single detector pairs, a succession of data sets representing, from a selected view, a succession of spatial images of the tissue, and an image data set related to differences between data of said successive data sets.
