Temperature-induced image drift is observed in commonly used cameras with CCD and CMOS sensors because their optomechanical design is not optimized to reduce this phenomenon. In every metrological application where the camera is used as a sensor for recording measurement images, image deformation caused by camera temperature changes significantly deteriorates the final properties of the application. Depending on the measurement scene, camera temperature changes can result in image position shifts of up to several pixels.
For many vision sensor-based measurement applications, image shifts or deformations of even 1 pixel can translate into errors observed in the measurement scene reaching up to several dozen centimeters or more. A very important issue is the fact that temperature-induced image drift is, on one hand, a widespread phenomenon, and on the other hand: a phenomenon that is little known and often overlooked in metrological analysis. Research shows that temperature-induced image drift is inherently random in nature. This lack of repeatability is the reason why software methods for reducing temperature drift cannot properly compensate for the described phenomenon.

Research shows that temperature-induced image drift is inherently random in nature. This lack of repeatability is the reason why software methods for reducing temperature drift cannot properly compensate for the described phenomenon.
The solution to these problems is Athermalized technology. It involves modifying the optomechanical construction of the camera by implementing a special compliant sensor suspension. Research indicates that the implementation of Athermalized technology eliminates the random nature of temperature-induced image drift, which in turn enables the implementation of a software compensation model. The end result is a reduction of temperature-induced image drift by over 80% and a significant improvement in the quality of recorded measurement images.
