Spatial distortion effects in infrared scene projectors, and methods to correct them, have been studied and reported in several recent papers. Such effects may be important when high angular fidelity is required of a projection test. The modeling and processing methods previously studied, though effective, have not been well suited for real-time implementation. However, the "spatial calibration" must be achieved in real-time for certain testing requirements. In this paper we describe recent efforts to formalize and implement real-time spatial calibration in a scene projector test. We describe the effect of the scene generation software, "distortion compensation", the projector, the sensor, and sensor processing algorithms on the transfer of spatial quantities through the projection system. These effects establish requirements for spatial calibration. The paper describes the hardware and software recently developed at KHILS to achieve real-time spatial calibration of a projection system. The technique extends previous efforts in its consideration of implementation requirements, and also in its explicit treatment of the spatial effects introduced by each of the distinct components of the overall system, as mentioned above.
