The principles of design of projectors of infrared (IR) scenes on the basis of micromirror technologies, which are the most promising devices for IR image generation, are analyzed. Several types of projectors based on these principles are considered from the viewpoint of functionality, noise minimization, and wavelength range in which these images are generated. Problems arising in design of IR scene projectors based on DMD technologies for generation of long-wave IR images are discussed.
