New technologies of infrared scene projection

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.
