Dynamic Complex Wave-front Modulation with an Analog Spatial Light Modulator

By Phil Birch, Rupert Young, David Budgett and Chris Chatwin

Abstract

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
