ALEXANDRIA, Va., Oct. 4 -- Thomas W. Hagler of Grass Valley, Calif., has developed a spectral component detection encoder spectrograph.
According to the abstract released by the U.S. Patent & Trademark Office: "An encoder spectrograph is used to analyze radiation from one or more samples in various configurations. The radiation is analyzed by spatially modulating the radiation after it has been dispersed by wavelength or imaged along a line. Dual encoder spectrographs may be used to encode radiation using a single modulator. An encoder spectrograph may be used wherein the first optics comprises a diffraction grating that is optimized for an annular-shaped intercept between the ...
