While infrared and thermal imaging are used in a variety of applications—surveillance, night vision, military, microscopy, and manufacturing to name a few—the primary objective in all these markets is to obtain images in low-light situations. As the systems become more cost-effective and the technology more developed, integrators are finding IR and thermal imaging to be the best solution for round-the-clock detection.

According to Dr. Jay James, Vice President, Cores and Components for FLIR Systems, some of the added features are image processing for better detail; video analytics for automated detection; threat assessment and response; higher sensitivity and high resolution for longer range performance and even better image quality.

Sensors Unlimited - Goodrich ISR Systems (Princeton, N.J.) offers an ultra-compact, high-sensitivity SU640KTSX indium gallium arsenide (InGaAs) shortwave infrared (SWIR) camera that requires no cooling; it is lightweight (less than 90g) and uses low power (less than 2.5W at 20° C), making it ideal for unmanned systems’ imaging requirements. The solid-state SWIR camera’s ability to image through many atmospheric obscurants like fog, haze or rain during daytime or nighttime makes the shortwave InGaAs high-sensitivity camera especially useful for unmanned aircraft for maritime intelligence and surveillance. Featuring room-temperature operation, InGaAs-SWIR cameras are lighter weight and consume less power than competing shortwave infrared, germanium-based cameras and mid- or long-wave infrared imagers, which generally require heavy and expensive cooling systems. The 640 x 512 pixel solid-state camera, with on-board non-uniformity corrections, captures full-sized images at 30 frames per second. The camera’s focal plane array features a 25-micron pitch with a wavelength response over the shortwave infrared spectrum from 0.9 to 1.7 microns.

Vision Components (Ettlingen, Germany) now offers a new VC4067 near infrared camera that is a flexible, powerful image processing system. It is optimally suited for security tasks such as perimeter protection and access control. Thanks to an integrated high-performance processor, the intelligent cameras execute all image-processing routines and can completely replace conventional, PC-based systems. Measuring just 110 x 50 x 35 mm, the units can be integrated even in small spaces. Optional robust housings provide protection for outdoor applications. Thanks to its spectrum near the infrared range, the VC4067/NIR camera meets all requirements for night-time use. The photosensitive technology ensures highly precise images at wavelengths up to 1,100 nm. Even at a distance, image capture is effective.  

Thermoteknix (Cambridge, United Kingdom) offers two new ranges of VisIR camera; the P (Predictive Maintenance) and S (Scientific) Ranges. Both ranges are available as 320 x 240 or 640 x 480 models with a full armory of features and tools designed for all maintenance and scientific/research applications. VisIR-P range cameras are state-of-the-art Predictive Maintenance thermal imagers available in high-resolution 320 x 240 or 640 x 480 models available in 60 or 9Hz versions. VisIR P range comes in a unique rugged industrial housing with articulated central optics pod for ergonomic and safe operation. With a high-contrast DayBright touch screen, VisIR P cameras provide precise temperature measurement and high definition thermal and visual image clarity in any lighting conditions. VisIR-P’s high resolution detectors and digital colour camera make surveys more efficient and cost-effective with easily-set personality profiles for multiple camera users. With integral LED illuminator/flash, laser pointer and voice recording, the P range is set to be the choice of thermal imaging cameras for professionals working in the industrial Predictive Maintenance arena.
