Abstract

Abstract The present invention employs a spectral and spatial combiner (132) that is capable of maintaining equal optical path lengths of each spectral beam so that a single combined bean (148) can be produced and can be employed in a number of different applications such as a color camera device (Figure 28), a color recording device (Figure 23), a graphics presentation device (Figure 27), an electronic color filter device (Figure 30), a color projector device (Figure 25) and a multi-­channel optical communication device (Figures 31 and 33).

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 210 words
A color imaging detector device for generating a color electronic image signal representative of a color image formed from an image beam (324) focused on an imaging plane comprising: imaging means (316) for focusing said color image beam (324) on said imaging plane; spectral separator means (312) disposed between said imaging means (316) and said imaging plane for spatially and spectrally separating said color image beam (324) into plurality of optical beams (326,328,330) such that each of said plurality of optical beams has a predetermined spectral range and optical axes that have optical path lengths that are substantially equal to said imaging plane, said spectral separator means comprising: first composite dichroic means for spatially and spectrally separating said color image beam into said plurality of optical beams so that each of said plurality of optical beams (326,328,330) has a predetermined spectral range and said optical axes are substantially parallel; second composite dichroic means for equalizing said optical path lengths of said optical axes of each of said plurality of optical beams (326,328,330) to said imaging plane; area array detector means (318,320,322) aligned with each of said plurality of optical beams on said imaging plane for generating a separate color electronic image signal for each of said plurality of optical beams.
Claim 2
Dependent Claim 210 words
A color imaging detector device for generating a color electronic image signal representative of a color image formed from an image beam (324) focused on an imaging plane comprising: imaging means (316) for focusing said color image beam (324) on said imaging plane; spectral separator means (312) disposed between said imaging means (316) and said imaging plane for spatially and spectrally separating said color image beam (324) into plurality of optical beams (326,328,330) such that each of said plurality of optical beams has a predetermined spectral range and optical axes that have optical path lengths that are substantially equal to said imaging plane, said spectral separator means comprising: first composite dichroic means for spatially and spectrally separating said color image beam into said plurality of optical beams so that each of said plurality of optical beams (326,328,330) has a predetermined spectral range and said optical axes are substantially parallel; second composite dichroic means for equalizing said optical path lengths of said optical axes of each of said plurality of optical beams (326,328,330) to said imaging plane; area array detector means (318,320,322) aligned with each of said plurality of optical beams on said imaging plane for generating a separate color electronic image signal for each of said plurality of optical beams.
