The purpose of the Dynamic Infrared Background/Target Simulator (DIBS) is to project dynamic infrared scenes to a test sensor; as an example, a missile seeker that is sensi-tive to infrared energy. The projected scene will include target(s) and background. This system was designed to present flicker-free infrared scenes in the 8pm to 12μm wavelength region. The major subassemblies of the DIBS are the Laser Write System (LWS), Vanadium Dioxide (V02) modulator assembly, Scene Data Buffer (SDB), and the Optical Image Translator (OIT). The process of writing a scene begins when the SDB is supplied with scene data from an imaging processing system. After processing, the SOB sends the data to the LWS which writes the scene onto a pair of VO2 modulators. This scene is then projected through the OIT giving a 6° x 6° picture to the sensor being investigated. This paper describes the overall concept and design of the infrared scene projector followed by some detail of the LYS and VO2 modulator. Also presented are brief descriptions of the SDB and OIT.
