1. A system for producing optical fringe patterns, comprising:
a first beam splitter configured to receive light from a light source;
a first spatial light modulator positioned to receive the light after reflection from the first beam splitter and to produce a first reflected light that is modulated in one or both of space and amplitude;
a second beam splitter configured to receive the first reflected light after traversal through the first beam splitter; and
a second spatial light modulator positioned to receive light after traversal through the first beam splitter and to produce a second reflected light that is modulated in one or both of space and amplitude, wherein the second beam splitter is configured to produce a set of fringe patterns, wherein each fringe pattern has a particular phase, polarization or intensity characteristic that is different from another one of the fringe patterns.
