Testo introduces new SuperResolution Technology which produces high-resolution thermal images for thermographic applications, 4 x more pixels and effectively double the resolution in all Testo thermal imagers via a software upgrade.
The new SuperResolution Technology, which represents a marked improvement in image quality for all Testo thermal imagers. With Testo's SuperResolution Technology, the use of recognised methods and algorithms considerably increases the resolution of thermal images: with four times as many readings and effectively double the resolution, each thermal image is considerably more detailed and this means greater reliability when taking thermographic measurements.
Testo's SuperResolution Technology, for which a patent is pending, makes use of two well-known, recognised methods. Firstly, a sequence of several images is saved each time a picture is taken. Calculations are made from this sequence of images, and the result is a higher-resolution image. Everyone has a natural tremor, which results in minimal movements while the thermal image is being taken, and this method utilises these movements. This creates a sequence of images that are minimally offset at random from each other. Testo's special algorithm uses the additional information and readings to create a higher-resolution image of the thermographed object.
Secondly, the image quality is improved based on detailed knowledge of the infrared lens characteristics. This is achieved by optimising the imaging properties of the lens by way of calculation. This procedure also helped the Hubble Space Telescope to record sharper images, for example.
Testo's SuperResolution Technology is not an interpolation method where artificial intermediate values are generated without obtaining additional information. Instead true readings are calculated, which can be regarded comparable to a higher detector resolution. Thus, e.g. from a 160 x 120 pixel image we get a 320 x 240 pixel image, and from a 320 x 240 pixel image we get a 640 x 480 pixel image. The geometric resolution of the SuperResolution thermal image is effectively doubled.
