Xenics, Europe's leading developer and manufacturer of advanced infrared detector solutions, is proving the breadth of its in-house design and production capabilities at SPIE DSS 2012. Xenics will announce a new megapixel SWIR detector, a new family of SWIR OEM modules and other sophisticated products ranging from detector arrays, easy-to-use modules and cameras, to multi-spectral image fusion devices for demanding applications such as night vision (active and passive), border security and search and rescue missions (SAR). Xenics exhibits in Hall B - Swing, booth# 1013.

Megapixel SWIR Focal Plane Array
At DSS 2012, Xenics will introduce the XFPA-1.7-1280, a focal-plane array in InGaAs technology, offering a very high resolution of 1280 x 1024 pixels at a pixel pitch of 17μm. Each pixel is equipped with an active anti-blooming feature. Its highest sensitivity area covers the standard NIR/SWIR range 0.9 to 1.7μm.

Power consumption below 0.6 W enables new ways of implementing advanced passive night-vision equipment for low-power search and rescue missions as well as autonomous flight operation of UAV/UAS under low light conditions.

The XFPA-1.7-1280 detector includes among others CDS (correlated double sampling), which allows lowest noise performance below 30 e-. The frame rate depends on the number of outputs selected: 50 Hz for two outputs, 100 Hz for four outputs, and high speed 200 Hz for eight outputs at a pixel clock of 40 MHz.Windowing allows for faster frame rates, which can be used for fast focusing on objects and scenes, as well as tracking of objects and suspected invaders.

SWIR OEM Modules
Newly introduced by Xenics is XenicsCore XSW-640, a high-resolution SWIR OEM module that offers high image quality and easy integration. The XSW-640 device supports demanding security applications such as border control, search and rescue, and passive night-vision applications as well as infrared imaging for portable and unmanned (airborne and land-based) vehicle payloads.

Especially suited for handheld and portable applications, XSW-640 modules are designed with small size, low weight and low power (SWaP) for long battery life.

To suit highly demanding applications, this newest SWIR OEM module XSW-640 is equipped with a single-stage thermoelectric cooler. Its high resolution of 640 x 512 pixels covers the SWIR range 0.9 to 1.7μm, which can be extended into the visible spectrum down to 0.6μm. The XSW-640 modules measure just 45 x 45 x 24 mm³ (without TE cooling). They consume about 3 watts of power (with TEC operation). Fixation holes for multiple lens mount provide an optical interface.

Image Fusion
Xenics' infrared detectors, modules and cameras cover the full spectrum from SWIR over MWIR to LWIR. For some applications, information coming from different spectral bands can provide vital information. In these cases, images coming from different cameras can be overlaid and fused, such that the image information is increased and can be used for further analysis and target recognition.

The Xenics XSW-640 SWIR module is well suited for image fusion applications as it can be readily operated in parallel with the XTM-640 thermal module for the LWIR. Due to their small sizes, they can be set-up in such a way that parallax is minimized.
