Claim Text:
1. A method comprising, in combination: (a) transmitting light through a first spatial light modulator, then through a second spatial light modulator, and then through a diffuser layer, such that a front side of the diffuser layer displays a time-varying sequence of images that is observable, by temporal integration, as an observable image; (b) using one or more processors (c) in accordance with the instructions, varying the actual pixel states of the pixels; wherein (A) the first spatial light modulator has a first spatial resolution, the second spatial light modulator has a second spatial resolution, and the observable image has a third spatial resolution, (B) the third spatial resolution is greater than the first spatial resolution and is greater than the second spatial resolution, (C) the observable image is displayed on the diffuser layer and comprises a projection, over an angular domain, of a light field incident on the diffuser layer, and (D) the optimization algorithm includes calculations involving a splitting variable, which splitting variable is a matrix that encodes an intermediate light field produced by the first and second spatial light modulators.
