Abstract

In a single light valve system, MTF curves and light efficiencies are calculated, which are only caused by the dark field method. Extended light sources in a regular arrangement with continuous spectral density in each of the three color channels—red, green, and blue—of the TV color projector are taken into account. Continuously tuned sinus modulation of the carrier gratings written into the control layer, acting as phase objects for the transmitted light, is chosen for the calculations. The results obtained are in good agreement with measurements.
