Scene Simulation Projector for 180 Degree LWIR Imager

摘要

Infrared dynamic scene simulation using resistive arrays and projection optics is becoming increasingly common for FLIR's and missile seekers that have narrow to moderatefields of view. This simulation capability enables an imaging system to be tested under a wide variety of simulated scenarios while mitigating some of the cost and complexity of field-testign. OPTICS 1, Inc. has completed a Phase I SBIR and is currently conducting Phase II activities to design, fabricate and test an infrared scene projector for wide-angle infrared imaging systems. Specifically, a need was identified to develop dynamic scene simulation capability for extremely wide-angle infrared imagers such as that under developemnt by OPTICS 1 for contract F08630-98-C-0022 in support of the Programmable Integrated Ordinance Suite (PIOS) program. This sensor images a full hemispheric field of view in the long-wave infrared (LWIR) waveband and therefore presents extreme challenges for scene projection. A paper under the same title was submitted and presented in 1999 defining the progress reached under the Phase I program. This paper describes progress under the Phase II program which will culminate in hardware delivered to the KHILS facility at Eglin AFB, FL in the fall of 2000. A brief overview of the units to be tested in included in Section 2 and a Similar overview of the projector layout and nominal performance is contained in Section 3. The majority of this publication discusses the analyses conducted for the projector assembly and specific issues that were address both from the analyses and in the specification of several components. This information is included in Section 4.
