Abstract:
1. A method for adjusting a spatial light modulator comprising an array of individually addressable channels, the method comprising: selecting a plurality of channel sets from the array of channels, wherein all the channels in each channel set are contiguously arranged; determining a first intensity value for first output radiation provided by all the channels in a first one of the channel sets; performing a first adjustment based at least on the first intensity value, the first adjustment including adjusting a control level of a first channel in the first one of the channel sets without adjusting a control level of a second channel in the first one of the channel sets; determining a second intensity value for second output radiation, wherein the second output radiation includes output radiation provided by some of the channels in the first one of the channel sets, and excludes output radiation provided by at least one channel in the first one of the channel sets; and performing a second adjustment based at least on the second intensity value, wherein the second adjustment includes adjusting a control level of a second channel in the first one of the channel sets.
