A novel projection system includes a light source, a phase modulator, an amplitude modulator, and a controller having temporal lightfield simulation capabilities. The phase modulator spatially modulates a lightfield from the light source to generate an intermediate image on the amplitude modulator. The amplitude modulator spatially modulates the intermediate image to form a final image. The controller models the phase state of the phase modulator during transitions between phase modulator frames and generates lightfield simulations of the intermediate image during the transition. The controller utilizes the lightfield simulations to generate and provide sets of amplitude drive values to the amplitude modulator at a faster rate than that at which the phase modulator is capable of switching.

Temporal modeling of phase modulators in multi-modulation projection

A dual-modulation projection system () includes a light source (), a phase modulator (), an amplitude modulator (), and a controller () having temporal lightfield simulation capabilities (). The phase modulator () spatially modulates a lightfield from the light source () to generate an intermediate image on the amplitude modulator (). The amplitude modulator () spatially modulates the intermediate image to form a final image. The controller () models the phase state of the phase modulator () during transitions between phase modulator frames and generates lightfield simulations of the intermediate image during the transition. The controller () utilizes the lightfield simulations to generate and provide sets of amplitude drive values to the amplitude modulator () at a faster rate than that at which the phase modulator () is capable of switching.
