Abstract.  We designed and developed a system to project video scenes in the near‐infrared (NIR) band based on digital micromirror devices (DMD) and digital signal processors (DSP). The system deals with the integration and interfacing of different embedded systems both in the field of digital light processing (DLP) and digital signal processing. On the DLP side, we integrated DMD, NIR light source, and projection optics. The input video source for the dynamic scene was generated using a DSP, where we designed and implemented a fast video‐retrieval algorithm. The proposed system can be used for testing and design of equipments operating in the NIR band. The system is tested for projecting NIR video at different projection distances using different driving powers of the NIR laser source, and it operated correctly and was capable of producing high frame rate of 180 frames per second (fps) without delay or distortion when viewed by an NIR camera.
