System and method for displaying high quality images in a dual modulation projection system

A controller for controlling a dual modulation projection system, said controller comprising:

• a processing unit configured to execute code;
• an interface coupled to receive image data indicative of at least one image to be displayed;
• and
• memory electrically coupled to store data and said code, said data and said code including
• a beam-steering drive generation module configured to generate beam-steering drive values for driving a beam-steering spatial light modulator (SLM) based at least in part on said image data,
• a lightfield simulation module configured to generate a simulation of a lightfield produced by said beam-steering SLM and incident on a second SLM based at least in part on said beam-steering drive values, wherein the lightfield simulation module is configured to choose a light propagation model used in the simulation from a plurality of available models based at least in part on said image data and/or said beam-steering drive values, and
• a modulation drive generation module configured to generate modulation drive values for driving said second SLM based at least in part on said simulation of said lightfield.
