Patent ID: 7190452

Claim:
A system means for detecting a light beam comprising: an area means for receiving the light beam; a means for spatially separating the light beam disposed in the area means to separate a small spatial portion of the light beam from an adjacent remainder of the light beam to provide a separated light beam and a remainder light beam and means to transmit the separated light beam to a means for spectroscopy; a means for imaging disposed in the area means to operably receive the remainder light beam to provide an image therefrom; and, a means for spectroscopy optically connected to the means for separating the light beam to receive the separated light beam to provide a spectrum therefrom, wherein the means for spectroscopy is located outside of the light beam and the means for spatially separating the light beam comprises a means for light redirection sized and located to intercept a small area of the light beam and change the direction of such small area toward the means for spectroscopy, and wherein the means for light redirection separates substantially all light incident thereon from the remainder light beam and imparts a small residual image in the remainder light beam corresponding to the location of the means for light redirection in the light beam.
