Abstract

Measure to evaluate holograms recorded with spatial light modulator(SLM), and optical systems to implement quantitative evaluation of the image quality are presented. We propose utilizing a pseudo-random diffuser with SLM to suppress speckle noise. High quality holograms have been obtained by using a high performance liquid-crystal display panel with a maximum contrast ratio as high as six hundred.
