Abstract:
A method for characterizing a primary radiant spectra of a projector includes projecting primary colors with a projector having a projector lamp and color filters. Measurements of each primary color are taken with a multi-band camera. Spectra of the color filters are estimated using the measurements from the multi-band camera. The primary radiant spectra of the projector are estimated using spectral data of the projector lamp and the estimated spectra of the color filters.
