摘要： We describe a phase modulating spatial light modulator (SLM). The SLM comprises a substrate bearing multiple SLM pixels, each of the SLM pixels comprising a MEMS (micro electromechanical system) optical phase modulating structure. The MEMS optical phase modulating structure comprises: a pixel electrode; a spring support structure around a perimeter of the pixel electrode; and a mirror spring supported by the spring support structure. The mirror spring comprises a mirror support and a plurality of mirror spring arms each extending between the mirror support and the spring support structure, and a mirror mounted on the mirror support. Each mirror spring arm has a spiral or serpentine shape. A voltage applied to the pixel electrode flexes the mirror spring and causes the mirror to translate perpendicularly to the substrate substantially without tilting.

摘要： This invention relates to methods, apparatus, and computer program code for the holographic display of images. We describe a method of displaying an image holographically. The method includes displaying a hologram on pixels of a spatial light modulator (SLM) and illuminating the SLM such that the image is displayed in pixels of a replay field (RPF) of the hologram. The method further includes subdividing the replay field into a plurality of spatially interlaced regions, and displaying holograms for each of the interlaced regions of the replay field sequentially at different times such that in an observer's eye the interlaced regions integrate to give the impression of the image and such that interference between adjacent pixels of the replay field is reduced.
