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： We describe a method of displaying an image holographically using a spatial light modulator (SLM), the SLM having a plurality of pixels, the method including: displaying a diffraction pattern on the pixels of the SLM; and illuminating the pixels such that light diffracted by said diffraction pattern on the SLM pixels includes a content of said displayed image. A variation in brightness of said displayed image across the displayed image is modulated by an intensity envelope determined by the diffraction pattern of an individual said pixel, for example a sinc envelope. The method further includes moving a peak or centre of gravity of the intensity envelope away from a zero order spot and towards a centre of the displayed image by imposing a pattern of phase delay across the SLM pixels, the pattern of phase delay repeating at a spatial interval corresponding to a pixel interval of the SLM.
