Xenics presents ready-to-integrate OEM modules for shortwave and thermal imaging and the latest technology developments in true image fusion (EN)

Leuven, Belgium / Orlando, FL, 24.04.2011 --- Xenics, Europe's leading developer and manufacturer of advanced infrared detector solutions, is proving the breadth of its innovation and production capabilities. At SPIE DSS 2011, Xenics will introduce “XenicsCores”, a new family of compact, high resolution infrared OEM modules as well as image fusion technology from different spectral ranges. Xenics will also demonstrate the latest upgrades of their proven products: GigE-Vision upgrade for Gobi-640, ThermographyStudio software for all MWIR to LWIR cameras, longwave thermal imaging with Onca-640, the smallest TE-4 cooled SWIR camera Xeva-2.5-320 at 200 Hz and new options for the high-speed Cheetah-640CL. Xenics exhibits in Palms Hall, Booth # 3119.

OEM modules and components
Up to now Xenics is well known for its in-house developed InGaAs infrared detectors with wide dynamic range and their versatile and compact camera systems. Xenics has chosen SPIE DSS for the presentation of a new family in between: Uncooled OEM modules as extremely compact and versatile cores which are ready to be integrated in the customer’s application and consume only low power.

The universal QTE connector allows for easy integration and offers the full flexibility to choose the preferred interface. This highlights the outstanding flexibility and cost-effectively solution of Xenics. The first two types are XSW-640 (Xenics Short Wave module) and XTM-640 (Xenics Thermal Module).

The XSW-640 camera module measures only 45 x 45 x 20 mm³ and is based on an uncooled InGaAs array (640 x 512 pixels) with 20 μm pixel pitch for the detection of short wave infrared radiation between 0.9 and 1.7 μm. The resolution of the analog/digital converter is 14 bit.

The XTM-640 or Xenics Thermal Module is optimised for the detection of thermal infrared radiation between 8 and 14 μm. It is equipped with an uncooled microbolometer array of 640 by 480 pixels with 17 μm pixel pitch with thermal sensitivity of 50 mK. It measures only 45 x 45 x 32 mm³, including advanced shutter design for optimal image performance in a small form factor housing,

Both modules need only 2.0 W from the 3.3 V supply and feature a frame rate of 50 Hz. Trigger input and output are available for synchronisation with external sources. Via its powerful readout and processing electronics, advanced NUC and image processing algorithms guarantee unparalleled uniform and crisp thermal images over a wide range of dynamic environments. The opto-mechanical design of the XenicsCores is adapted to accommodate customer specific lens and interface requirements.

Image fusion
One of the latest technology trends is a combination of images, acquired in two different spectral ranges. The fusion of visual and SWIR or LWIR imaging or alternatively SWIR and LWIR enhances the vision of a scene and can set thermal accents in SWIR or visual images. For this purpose the Meerkat Fusion camera is equipped with three cameras for the visual, SWIR and LWIR spectral ranges and unites the best of all worlds. Convenient software performs the image fusion of two cameras taking into account different resolutions of the sensor arrays and different focal lengths of the optics. It delivers a picture that is segmented into regions using specific properties such as movement or high temperature. Therefore image fusion is well suited for early detection of wildlife fires and indoor search and rescue operations.

Security products
The Meerkat camera series are high performance but affordable infrared camera solutions for demanding international security communities. The plug-and-play IR camera configurations cover all the regions of the infrared spectrum: Shortwave Infrared (SWIR), Midwave infrared (MWIR), Longwave Infrared (LWIR) and Very Longwave Infrared (VLWIR). The Meerkat Fix for example is a powerful surveillance and monitoring camera in a fixed housing with an uncooled LWIR thermal imager. This complete system can be installed very easily with generic Ethernet connection in a local area network (LAN). 

For powerful and multi-purpose airborne imaging platforms the Pumair-170DW (Dual Wavelength) is equipped with two state-of-the-art infrared cameras: a longwave (LWIR) and a shortwave (SWIR) camera in one of the smallest lightweight housings on the market. Its two-axis gyro stabilized (better than 100 microRad) mini-gimbal comes in a revolutionary L-shape design for easy integration and low power consumption.

Upgrades of proven products
The features of proven products are continuously improved. Here are some examples:

Gobi-640-GigE
The uncooled thermal camera Gobi-640 is now also available with a GigE Vision interface, which opens this high-resolution (640 x 480 pixels) camera to new application areas. It operates in the 8-to-14 μm wavelength range and detects temperature differences as small as 0.05 ºC.

ThermographyStudio
ThermographyStudio is a complete thermal analysis software suite with realtime recorder function and powerful built-in measurement and analysis functions for all MWIR and (V)LWIR cameras like automatic hot spot detection, multi point trend, box-line trend, area trend, isotherms, histograms, envelope profiles, line profiles, region-of-interest statistics and many more. Its clearly-structured and easy-to-use user interface allows intuitive usage of the software and reduces training needs and costs. Professional and easy to read reports are created by a few mouse-clicks. ThermographyStudio will be demonstrated on the Gobi-384, a smart uncooled microbolometer camera for thermal imaging in the LWIR range.

Onca extended into (V)LWIR
The high-end IR and thermal imaging platform Onca with cooled detector is excellently suited for R&D environments as well as industrial process monitoring, high speed imaging, target signature radiometric data collection, tracking and IR spectroscopy. The various sensor types MWIR-InSb, MWIR-MCT, LWIR-QWIP and LWIR-MCT cover extended wavelengths at a broad sensitivity range. The Onca-(V)LWIR-MCT is a Long to Very Longwave thermal camera for special applications requiring longer wavelengths and extra spectral response filters. On the other hand the Onca-LWIR-QWIP camera excels in harsh environments with sharp and stable operation for long range imaging.

Xeva-2.5-320 (MCT)
The smallest TE-4 cooled SWIR camera is now available in a 200 Hz upgrade version. It delivers superior performance for reliable research tasks, allowing faster hyperspectral imaging at frame rates of 60, 100 or 200 Hz.

Cheetah-640CL
The Cheetah-640CL camera is now available in a three-stage water-cooled upgrade for the 120 Hz version. Cheetah-640CL TE3 offers high resolution, compact build and a dedicated low-noise InGaAs detector array for 0.9 to 1.7 μm. The TE3 cooled sensor and the water cooled camera head make the Cheetah-640CL TE3 highly sensitive, achieving ultra-low dark current characteristics at long integration times to operate at low light levels in the SWIR range, as needed in semiconductor failure analysis or luminescence spectroscopy.

Conference contributions
At the SPIE DSS conference two papers will be presented highlighting Xenics’ expertise in image fusion with the Meerkat Fusion and fast line scan detectors with high resolution:

The development of a multiband system for early detection of wildlife fires and indoor search and rescue operations Conference 8029A, Tuesday, 26. April 2011, 5:20 PM – 5:40 PM.

In the framework of the EU Firesense project (FP7-244088), several visible and infrared cameras are tested for the early detection of wildfires and to enhance the vision through smoke in indoor applications (e.g. parking lot fires). Images and detection are based on broadband imagery, as well as on imaging of narrow band features. This work includes as well the sensor fusion to combine images from multiple wavelength bands and the algorithms applied for the image segmentation and automatic fire and smoke detection.

A 40 ksamples/sec spectrometer based FBG interrogator, capable of simultaneously measuring more than 16 FBG sensors. Conference 8028, Thursday, 28. April 2011, 4:20 PM – 4:40 PM.

A fast spectrometer based FBG interrogator will be discussed. This unit is constructed around a fast linear InGaAs array with 1024 pixels and capable of reading out 40 000 lines per second. This array is integrated in a double reflective grating spectrometer, dispersing the spectra in the [1510 – 1590 nm] band. The signal treatment electronics is capable of determining the peak wavelength position of at least 8 birefringed FBG sensors or 16 single FBG sensors at the data rate, supplied by the image sensor.

Extreme compact size and low weight

Given the extremely compact size and low weight of the Xenics XS-1.7-320 SWIR camera it was extremely easy to integrate it into our existing optical setup.
