The system features an all-reflective optical system, internal and external thermal reference sources, a visible camera-based sighting/alignment capability, modular MWIR and LWIR detector/filter subassemblies, flexible control/display software, and a sophisticated graphical user interface (GUI). We present prototype performance data describing the instrument's thermal sensitivity, radiometric accuracy, spectral resolution, calibration, and other key parameters.

Advanced E-O test capability for Army Next-Generation Automated Test System (NGATS)

SPIE Proceedings, 2015

Santa Barbara infrared (SBIR) has designed, fabricated, and delivered three (3) prototype FEO for engineering and logistics evaluation prior to anticipated full-scale production beginning in 2016. In addition to presenting a detailed overview of the FEO system hardware design, features and testing capabilities, the integration of SBIR’s EO-IR sensor and laser test software package, IRWindows 4™, into FEO to automate the test execution, data collection and analysis, archiving and reporting of results is also described.

OASIS: cryogenically-optimized resistive arrays and IRSP subsystems for space-background IR simulation

The OASIS array is a 512 x 512 device featuring high output dynamic range, a selectable analog/digital scene data interface, and the capability to operate from cryogenic to ambient substrate temperatures-thereby providing an enabling technology for projection of simulated radiance of space-background scenes. Prototype emitter production has been completed at RTI International in support of initial deliveries. The OASIS array package incorporates novel electrical bussing schemes optimized for the OASIS RIIC and a modular architecture to allow user re-configuration of both window and emitter shield. The OASIS package leverages LFRA operation features, and supports both ambient and cryogenic chamber-based operation with a minimum of mechanical and electrical re-configuration. The OASIS close support electronics (CSE) supports both analog and digital input data modes, while providing easy electronic connection between arrays installed in the cryogenic chamber and the external control and scene-generation systems. We present a technical overview of the OASIS array/package and CSE designs, and will report on measured radiometric performance from prototype OASIS arrays.

<title>Large format resistive array (LFRA) infrared scene projector (IRSP) performance and production status</title>

Technologies for Synthetic Environments: Hardware-in-the-Loop Testing XI, 2006

ABSTRACT SBIR has completed development of the Large Format Resistive Array (LFRA) Infrared Scene... more ABSTRACT SBIR has completed development of the Large Format Resistive Array (LFRA) Infrared Scene Projector (IRSP) and shipped the first production system. Nine more systems are in production and will be shipped to several US Government customers on approximately six week centers. The commercial name of the LFRA IRSP is Mirage XL. System performance meets a broad range of program requirements and SBIR has been extremely successful in producing this ground breaking projector. Tests performed on System #1 reveal broad compliance to the specification and, in particular, outstanding emitter array performance. Key emitter requirements that have been met or exceeded include Operability, Maximum Apparent Temperature, and Array Uniformity. Key System specifications are: Large-format emitter array (1024x1024); High maximum apparent temperature (&gt;700K) 200 Hz full-frame operation; 400 Hz static window mode (1024x512); Non Uniformity (uncorrected) &lt;10%.

We describe the rationale for radiometric calibration, an analysis of error sources typically encountered by investigators during calibration of infrared imaging cameras when using target projectors, and a strategy for performing an absolute system end-to-end radiometric calibration with emphasis on high accuracy and ease of use.

Vantablack properties in commercial thermal infrared imaging systems

Vantablack® is an ultra-black coating developed by Surrey NanoSystems Ltd. in the United Kingdom and supported in the USA by Santa Barbara Infrared, Inc. Vantablack® was originally developed for satellite-borne blackbody calibration systems and is now available in two versions, either directly applied to surfaces using vacuum-deposition technology (Vantablack®), or by spraying and then post-processing (Vantablack®-S). In this paper, we present the results of Vantablack®-S coated cold shields and blackbody calibration sources; and compare performance to other industry standard black coatings. Also included are results of environmental testing on coated surfaces demonstrating that, while they are not meant to be touched, they withstand extremes of heat, vacuum and thermal cycling as well or better than other black coatings.

The "RAD-9000" design covers the 3-5 mm and 8-12 mm spectral bands, provides thermal sensitivity of better than 40 mK, supports object temperatures from 278-373 K, and delivers better than 2% spectral resolution (Dl/l). The RAD-9000 features computer-controlled operation, an intuitive graphical user interface (GUI), motorized focus adjustment, VIS-CCD sighting/alignment capability, less than 2 mrad detector IFOV, and an internal ambient reference for background subtraction and enhanced stability. In addition to high-performance relative radiometry, the RAD-9000 offers a high degree of absolute radiometric accuracy by utilizing a dedicated radiometric reference module. The reference module incorporates two 8-inch, variable temperature, high-emissivity extended sources to provide a stable, accurate absolute radiometric reference external to the main optics.
