Dynamic complex wave-front modulation with an analog spatial light modulator
A method of producing an arbitrary complex field modulation by use of two pixels of an
analog ferroelectric spatial light modulator (SLM) is demonstrated. The method uses the
gray-scale modulation capabilities of a SLM to spatially encode the complex data on two
pixels. A spatial filter is used to remove the carrier signal. This technique gives fast gray-
level amplitude and phase modulation.
