Abstract: The new development of infrared scene projection technology which emerged in recent years were summarized in this paper. Some new typical methods were introduced, for example VLSI- membrane-mirror-light-modulator scene projection technology, mid-wave infrared light emitting diodes for using in infrared scene projection, infrared liquid crystal light valve based on polymer/liquid crystal, a new electron beam-addressed reflective spatial light modulator and projection system for HWIL scene generation, an improved CMOS-compatible bulk-silicon-micromachined microemitter for dynamic infrared scene projector, single-layer SiGe infrared wide-band microemitter arrays by MEMS technology, and so on. At last, the development trends of the infrared scene projection techniques was analyzed.
