Abstract. To achieve the full complex modulated range of the cascaded twisted nematic liquid crystal spatial light modulator ͑TNLC-SLM͒, we propose and demonstrate a novel amplitude compensated technique. Optical reconstructions of complex digital holograms with higher image quality are discussed in both analytical and experimental results.
A dynamic optical reconstructed system for digital hologram is developed using two commercially available twisted-nematic-liquidcrystal spatial light modulators (TNLC-SLMs), which are operating in the amplitude-and phase-mostly modulation modes, respectively. The complex modulated properties of this cascaded two TNLC-SLMs can be analyzed by the Jones matrix method and also be measured in experiment. According to the characteristics of our cascaded SLM module, the dynamic optical reconstruction of the digital hologram with the complex-values can be demonstrated. Both analytic and experimental results are presented and discussed.
