摘要
We propose and demonstrate the characterization of complex modulation of liquid crystal devices by phase-shifting digital holographic microscopy with lensless imaging configuration. The complex-modulated wavefronts of the liquid crystal spatial light modulator are measured directly from the reconstructed field of the phase-shifted digital holograms. The characteristics of various operation modes of the commercial twisted nematic liquid crystal devices are specified as functions of input gray levels.
