Abstract

The MIM active matrix liquid crystal device with pixel pitch of 30 μm has been developed and its holographic display characteristics and application to 3D holography have been studied. In the system, a CCD camera reads holographic fringes with quite low career spatial frequency and the fringes are transferred and displayed on the SLM. We use the spatial filtering technique to reduce 0 th. order diffracted light on reconstruction. Recent results of polarization filtering to remove 0 th. order light and of 3M pixel LCDs using MIM technology are presented.
