Patent abstract
A three-dimensional object imager uses infrared light at different wavelengths to triangulate depth information of the object from wavelength-dependent detection of the infrared image of the object. The depth information is obtained by determining wavelength of infrared light impinging on different pixels of the array. The wavelength may be determined by breaking each pixel into a plurality of sub-pixels, each sub-pixel having its own spectral selectivity to light at different infrared wavelength. For eye imaging or eye tracking applications, this enables the preservation of an unobstructed field of view of the eye while obtaining real-time, dynamic information about eye position and orientation in an non-intrusive, inconspicuous manner.
