The advantages of LWIR SLS thermal cameras

For many years, high-speed visible cameras offered the ability to stop motion on fast-moving objects and provided unique insight through slow-motion playback for high-speed applications such as ballistics, munitions and tracking applications. Unfortunately, their thermal IR camera counterparts didn’t offer the snapshot speeds, high frame rates, and wide temperature measurement ranges necessary to be useful for these same testing applications. 

The authors of this article discuss how FLIR Systems has developed next-generation high-speed infrared readout integrating circuits (ROICs) and new strain layer superlattice (SLS) detector materials, which they have integrated into commercially available infrared cameras that can provide the much-needed speed and dynamic range to meet the challenges of high-speed thermal testing applications on the range.

Further the authors describe how these new FLIR Longwave Infrared SLS detectors offer greater than an order of magnitude faster integration times (snapshot speeds) than indium antimonide (InSb) detectors when imaging the same temperature range. A second benefit of these LWIR SLS thermal cameras is that they can operate over a wider temperature range (e.g. -20C – +150C) in a single integration.

The article concludes that advances in ROIC design allowing for shorter integration times, faster frame rates and better linearity, coupled with the new LWIR SLS detectors that deliver shorter integration times, wider temperature bands and better uniformity mean that finally useful IR cameras for high-speed thermal measurement on ballistic test ranges are available.

FLIR Systems specialises in technologies that enhance perception and awareness.  The company brings innovative sensing solutions into daily life through its thermal imaging and visible light imaging technology and systems for measurement, diagnosis, location and advanced threat detection.  Its products improve the way people interact with the world around them, enhance productivity, increase energy efficiency and make the workplace safer.

FLIR Systems has six operating segments – surveillance, instruments, OEM and emerging markets, maritime, security and finally, detection. Of these six, ‘instruments’ is of greatest interest to trade and industry and the second largest segment in the company’s portfolio. This division provides devices that image, measure and assess thermal energy, gases and other environmental elements for industrial, commercial and scientific applications.

These products are manufactured across five production sites, three in the USA and two in Europe; Sweden and Estonia.

A model to suit every application and budget
The options that FLIR Systems provides for measuring temperature and studying thermal performance have never been greater.  Not only does the company offer a huge range of models to suit all thermal application needs but the technology is also affordable and very easy to use.  Thermal cameras now come in various shapes, sizes and degrees of sophistication and FLIR continues to invest heavily in the development of new and complementary technologies to differentiate itself from competitors.

An important milestone in the development of thermal imaging has been the introduction of the FLIR Lepton® core, a micro longwave detector, the size of a mobile SIM.  This has allowed thermal imaging to be repackaged to meet the needs of an even wider audience and, in combination with another new technology called Infrared Guided Measurement – IGM™ – has led to the development of a range of test and measurement meters with imaging capability.

Another important growth area for FLIR thermal imaging is in continuous monitoring to assure quality and safety.  Through its introduction of discrete fixed mounted thermal cameras which are fully compliant industry standard plug-and-play protocols, FLIR Systems has provided industry with infrared machine vision which is instantly ready for quick and easy network installation.

Protecting assets and people from fire is an area for which thermal imaging is least known but, thanks to FLIR Systems’ development, it is now one of the most cost-effective methods available.  Its application flexibility and rapid return on investment present an attractive proposition for any site or safety manager.
