Paper Abstract

We apply transmission gratings under Littrow incidence to produce polychromatic colors by additive color mixing. Parametric optimization of gratings is employed to confirm high efficiency. In addition, we show that the system can yield the same color from two different light sources with arbitrary spectra, i.e. system can produce metameric colors.
