AbstractOPTRA proposes the development of a fieldable two-color infrared (IR) source simulator based on fused projected images of two digital micromirror devices (DMDs), one for each IR spectral band. Our approach employs a broadband thermal IR source with a series of spectral filters to flood the DMDs with characteristic "red spike" and "blue spike" IR energy, respectively. The relative intensities of the two spectral bands are controlled through the duty cycle of the "on" image reflected by each DMD. We fuse the two simulated images and project the composite with a telescope of aperture diameter chosen to meet the radiant intensity requirements of this application. The overall approach offers a realistic IR source image of characteristic spectral, temporal, and radiant intensity properties of an actual missile plume.
