Classification: CPC G  H | IPC G  H

Claim 11:
12. The method of claim 5, wherein modulating the intensity of light passing through the pSLM includes:
identifying a maximum intensity of light in the reference illumination landscape, herein ITmax;
identifying the segment with a lowest intensity of the reference illumination landscape, herein Smin, having an intensity ISmin; and
monitoring the intensity of Smin while increasing the power of the light source to a power level P2 wherein the intensity of Smin is raised to ITmax,
separately reducing the intensity of light reaching the image sensor through the segments of the pSLM that are greater than ITmax at power level P2, by separately allowing each segment to transmit light while the remaining segments block at least a portion of light, and, for each such segment, incrementally increasing absorption of the pSLM at a first incremental value until the segment exhibits and intensity of ITmax or below, wherein, if the intensity falls below ITmax, the method further comprises incrementally decreasing the absorption of the pSLM at that segment at a second incremental value that is less than the first incremental value.
