Abstract:
1. A mechanical-optical transducer comprising: a readout illumination source, said readout illumination source having a first light source providing light of a first wavelength and a second light source providing light of a second wavelength, said first light source spaced from said second light source by an interval; an image sensor array including a plurality of imaging pixels for responding to light from said readout illumination source; a mechanical-optical device including a plurality of micro mirrors forming a reflective surface disposed to selectively reflect light from said readout illumination source to corresponding said imaging pixels in said image sensor array, and an aperture plate disposed in an optical path between said mechanical-optical device and said image sensor array, said aperture plate having an imaging aperture for spatially filtering illumination from said readout illumination source such that either light of the first wavelength or light of both wavelengths is selectively provided to at least one of said imaging pixels.
