Abstract

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.
