Systems and methods for interweaving infrared and visible moving image data using a single optical system and imager device based on an infrared input signal and a visible input signal are disclosed. Infrared image frames can be substituted in for complete visible image input frames or for partial visible image input frames, i.e. substituting in an infrared image input frame for one or more of the color channels in one or more visible image input frames. Moving video or computer-generated moving graphics can include both infrared and visible image data to be displayed users viewing the resulting images with and without night vision imaging devices. In particular, the system and method can be used in projection systems for night-vision imaging device team training simulators to reduce the cost of the system while increasing the ease of use and performance of such systems.
