Performance improvements in Large Format Resistive Array (LFRA) InfraRed Scene Projectors (IRSP)
Santa Barbara InfraRed (SBIR) is producing high performance 1,024 × 1,024 Large Format Resistive emitter Arrays (LFRA) for use in the next generation of IR Scene Projectors (IRSPs). The demands of testing modern infrared imaging systems require higher temperatures and faster frame rates. New emitter pixel designs, rise time enhancement techniques and a new process for annealing arrays are being applied to continually improve performance. This paper will discuss the advances in pixel design, rise time enhancement techniques and also the process by which arrays are annealed. Test results will be discussed highlighting improvements in rise time, uniformity and reduced numbers of defective pixels.
