What makes our Stress Imaging system unique is the type of thermal imaging sensor at its heart. Rather than taking the well-established path of developing a system utilising a cooled, photonic sensor, which are the most sensitive sensors available, 1MILLIKELVIN did the opposite. We prioritised ease-of-use, ruggedness, and simplicity as our starting point, which required the use of uncooled, microbolometer technology.
This approach came with a serious technical challenge though, as the lower sensitivity and higher latency of these sensors make Stress Imaging more difficult. We pushed ahead undeterred, with the hope that the significant benefits in usability and deploy-ability would outweigh any loss in sensitivity. What eventuated was a rather surprising result. Due to the distinctive nature of the noise in an uncooled bolometer sensor it starts out noisier but as processing of the video stream continues it quickly catches up and ultimately outperforms a photonic sensor.
The result is a Stress Imaging camera that is easier to use, more rugged, more affordable, more sensitive, and better suited for real-world use.
