Abstract:
A contact image sensor having an illumination source; a first SBG array device; a transmission grating; a second SBG array device; a waveguiding layer including a multiplicity of waveguide cores separated by cladding material; an upper clad layer; and a platen. The sensor further includes: an input element for coupling light from the illumination source into the first SBG array; a coupling element for coupling light out of the cores into output optical paths coupled to a detector having at least one photosensitive element.

Claim (Index 20):
The apparatus of  claim 1  wherein said waveguide provides a detector waveguide in a contact image sensor comprising:\n an illumination source providing a collimated beam of light; \n an illuminator waveguide configured for propagating said light in a first total internal reflection path and containing a first array of grating columns; \n a detector comprising at least one photosensitive element; \n a platen; \n said detector waveguide configured for propagating light in a second total internal reflection path and containing a second array of grating columns; \n at least one beam steering grating disposed between said platen and said waveguide; \n a first waveguide coupler for coupling light from said illumination source into said illuminator waveguide; and, \n a second waveguide coupler for coupling light out of said detector waveguide into an output optical path, \n wherein said grating elements of said first array are orthogonal to said first total internal reflection path and said grating elements of said second array are orthogonal to said second total internal reflection path, \n wherein said columns in said first and second grating arrays are switched in cyclic fashion with only one said column element in each array being in a diffracting state at any time.
