Thermal imaging and biometric security applications opened up with infrared
Infrared (IR) cameras, which capture infrared energy instead of visible light, have begun to appear in smartphones and may open up new applications for camera technology, according to ABI Research.
IR cameras serve many useful functions in enterprise, as the IR energy provides a sixth sense view of heat, noted ABI. The military used such devices for years to ‘see through’ objects in either day or night, and now, IR cameras are showing up in mobile phones.
In its recent teardowns of the world’s first thermal imaging smartphone, CAT S60, and the highly publicised and recalled Samsung Galaxy Note7, ABI Research has found that the new trend of incorporating IR cameras into mobile phones is only just heating up.
“The simplicity of transitioning between IR and visible light views and the extra sense provided by the IR detection is astonishing,” said Jim Mielke, MD and VP of teardowns at ABI Research. “The infrared cameras in these phones produce good quality photos, as most phones today do, but then offer an added layer of resourcefulness by capturing a completely different view of the world.”
Heavy machine operator Caterpillar designed the CAT S60 to provide an inexpensive solution to enterprises looking to use thermal imaging in the workplace. The phone allows workers from manufacturing to field services to capture thermal images that detect changes in heat up to 100 feet away and can read specific temperatures between 50 and 75 feet from the user. The phone integrates a FLIR IR camera, in addition to a normal 13MP rear and 5MP front camera.
The Samsung Galaxy Note7, on the other hand, incorporated an IR camera not for photos but for security. ABI Research finds that the front-facing IR camera uniquely identifies the phone owner by characteristics of their eye, taking biometric identification to the next level.
“The benefits of IR imagery are not well known by the masses, but with a little education via marketing by the handset manufacturers, IR cameras could easily become a significant differentiator in smartphones,” concluded Mielke. “Practical uses include air leak detection around the home, temperature measurement, individual biometric identification, and even detection of burglars hiding in the bushes.”
