Abstract: Exclusive rights to the use of ultra-black Vantablack S-VIS surface coating in blackbody calibration sources has been agreed between Surrey NanoSystems and Santa Barbara Infrared. The unparalleled broadband absorption of Vantablack S-VIS makes it ideally suited to enhancing the performance and utility of Santa Barbara Infrared’s (SBIR) precision electro-optical instrumentation, reinforcing its leadership position in military, aerospace IR/FLIR testing and simulation markets. Initially, SBIR is using Surrey NanoSystems' UK facility to apply the Vantablack coating, while it establishes a local facility to serve the North American defense, aerospace and electro-optical markets. Commenting on the agreement, SBIR's President Steve McHugh notes: "The superb broad band absorption of Vantablack coatings, and the highly uniform deposition layer, helps us to create blackbody sources offering extremely high radiometric performance without caveats - greatly enhancing ease of use." Surrey NanoSystems’ CEO David Wong adds: “We’re really pleased to have Vantablack recognized by SBIR, who have a reputation built on performance and precision. We’re also delighted to have a partner to simplify procurement and provide local support for Vantablack coatings in North America. We see this as crucial to serving such an important market”. Surrey NanoSystems' Vantablack is the world's blackest surface coating material for the UV to FIR spectrum. It employs an innovative nanomaterial structure that absorbs virtually all incident light. Vantablack was developed for space-borne imaging applications and offers exceptional IR absorption and excellent thermal, mechanical and environmental stability - attributes which uniquely qualify it for the most demanding applications. The material has already achieved space heritage with its recent deployment on an Earth observation satellite. The S-VIS version of Vantablack traps over 99.8% of near- and mid-infrared wavelengths hitting its surface. It is applied using a simple spraying technique before being post-processed to achieve its exceptional broad band absorption characteristics and near-perfect Lambertian performance. This absorption is maintained over a wide range of wavelengths and viewing angles, far outstripping conventional black paints and other vacuum-deposited coatings. These characteristics are critical for SBIR’s specialized equipment, where compliance with rigorous US defense standards, long-term stability and traceable precision are essential attributes. The active element of Vantablack S-VIS is a functionalized carbon nanotube matrix. The coating is applied using a proprietary process that includes a number of pre- and post-application steps to achieve its ultra-low reflectance. The process is scalable and suitable for high-volume production on both small and large substrates, and on complex 3D surfaces. Vantablack S-VIS can be applied to a variety of substrates, with the only major constraint being the ability of the substrate to withstand process temperatures of 100-150 degrees Centigrade, making the coating suitable for application onto many popular types of engineering-grade polymers and composite materials. Since its launch in spring 2016, well over 100 Vantablack S-VIS projects have already been completed, including in space-borne instrumentation and military optical systems. The agreement with SBIR provides the next platform for the further adoption of the technology.

Electro Optical technology continues to advance, incorporating developments in infrared and laser technology into smaller, more tightly-integrated systems that can see and discriminate military targets at ever-increasing distances. New systems incorporate laser illumination and ranging with gated sensors that allow unparalleled vision at a distance. These new capabilities augment existing all-weather performance in the mid-wave infrared (MWIR) and long-wave infrared (LWIR), as well as low light level visible and near infrared (VNIR), giving the user multiple means of looking at targets of interest. There is a need in the test industry to generate imagery in the relevant spectral bands, and to provide temporal stimulus for testing range-gated systems. Santa Barbara Infrared (SBIR) has developed a new means of combining a uniform infrared source with uniform laser and visible sources for electro-optics (EO) testing. The source has been designed to allow laboratory testing of surveillance systems incorporating an infrared imager and a range-gated camera; and for field testing of emerging multi-spectral/fused sensor systems. A description of the source will be presented along with performance data relating to EO testing, including output in pertinent spectral bands, stability and resolution. © 2010 Copyright SPIE - The International Society for Optical Engineering.

Performing a good non-uniformity correction is a key part of achieving optimal performance from an infrared scene projector. Ideally, NUC will be performed in the same band in which the scene projector will be used. Cooled, large format MWIR cameras are readily available and have been successfully used to perform NUC, however, cooled large format LWIR cameras are not as common and are prohibitively expensive. Large format uncooled cameras are far more available and affordable, but present a range of challenges in practical use for performing NUC on an IRSP. Santa Barbara Infrared, Inc. reports progress on a continuing development program to use a microbolometer camera to perform LWIR NUC on an IRSP. Camera instability and temporal response and thermal resolution are the main difficulties. A discussion of processes developed to mitigate these issues follows. © 2010 Copyright SPIE - The International Society for Optical Engineering.

Test Program Set (TPS) software development for Electro-Optical (EO) testing has traditionally been an expensive and lengthy process. A major cause of this has been the development of new test executive software on an ad hoc basis for each program. Furthermore, there have typically been different needs for production versus lab environments with production needing a set of standard tests, while users in a lab environment requiring the capability to modify certain aspects of their tests as needed. At Santa Barbara Infrared, a new architecture for TPS development has been engineered that addresses these concerns. The new architecture can host a complete TPS development environment that eliminates the need for a separate test executive. It supports EO testing in both engineering development and production testing through the use of user editable test scripts along with distinct user accounts and privileges. The new architecture is unit under test (UUT) centric, allowing a user to define UUT parameters once and easily share the results between tests. In this article we will review the new architecture and give examples of TPS development under that architecture. © 2011 SPIE.

The Minimum Resolvable Temperature Difference test (MRTD) is one of the tests typically required to characterize the performance of thermal imaging systems. The traditional test methodology is very time intensive, requiring data collection at multiple temperatures and target frequencies. This paper will present an alternate methodology using a controlled blackbody temperature ramp rate. This allows selection of the temperature at which a target is determined "resolveda" without stopping. Test results using the traditional method will be compared to test results using this alternate method. © 2014 SPIE.

Drive circuit (100, 200, 300, 400) for LED thermal emitters in pixel elements of an infrared scene projector (IRSP). At least two current sources (Q1, Q2, Q5) provide output currents (I1,I2,I3) which may be summed and provided to a single LED (150), or provided independently to two or more LEDs (450A, 450B). The current sources may have different gains (G1, G2, G3), and different turn-on voltages (Voffset). This allows for different resolutions for different ranges of apparent temperatures, such as high resolution in a low range and low resolution in a high range, thereby facilitating a digital implementation of the drive circuit(s).

Sub-arrays such as tiles or chips having pixel elements arranged on a routing layer or carrier to form a larger array. Through-chip vias or the like to the backside of the chip are used for connecting with the pixel elements. Edge features of the tiles may provide for physical alignment, mechanical attachment and chip-to-chip communication. Edge damage tolerance with minimal loss of function may be achieved by moving unit cell circuitry and the electrically active portions of a pixel element away from the tile edge(s) while leaving the optically active portion closer to the edge(s) if minor damage will not cause a complete failure of the pixel. The pixel elements may be thermal emitter elements for IR image projectors, thermal detector elements for microbolometers, LED-based emitters, or quantum photon detectors such as those found in visible, infrared and ultraviolet FPAs (focal plane arrays), and the like. Various architectures are disclosed.
