The SuperResolution technology from testo is designed to enhance the resolution and number of readings of thermal images in thermography applications.
Thermography of small or extremely distant objects in various industrial and trade applications requires better image resolution and more readings in the thermal image for a more detailed and clearer representation of the object.
The Testo SuperResolution technology improves the usable, geometric resolution of the thermal image by a factor of 1.6 and provides four times more readings to offer more details on every thermal image and greater reliability during every thermographic measurement.
These thermal images with SuperResolution quality are achieved by combining super-sampling and deconvolution technologies, which can be used by Testo thermal imagers thanks to a complex algorithm.
The SuperResolution technology uses the natural hand movement to take multiple slightly offset photos in rapid succession, which can be converted into high-resolution images using the algorithm.
In comparison to digital cameras, infrared detectors only have a low resolution, which can cause problems if small objects, sometimes even smaller than a single pixel need to be detected and measured.
Often, the small measuring object only makes up a fraction of the entire radiation measured, which means that it may disappear into the background and no longer be recognisable. Even if it is large enough to make up a significant portion of the radiation, the influence from the background can still cause the measurement value to be between the temperature of the measuring object and that of the background resulting in the recording of a distorted value.
This problem is particularly common in microelectronics where thermographic images are taken of objects for which a particularly small and fine resolution is required. This challenge is also common in the field of building thermography where objects can be positioned many metres away.
The Testo SuperResolution technology makes it possible to depict more real temperature measurements without using a large detector, helping to correctly measure smaller measuring objects. Unlike simple interpolation procedures, the SuperResolution technology increases the measurement resolution and level of detail.
