2/2Testo AG, Präsentationstitel (Version), Ersteller, Datum, Vertraulichkeitsstufe

Takes multiple image very rapidly one after another

What is the Technology Behind ?

320 240 i l320 x 240 pixels

Four times as many readings – easily accessible in

The analysis software on your PCy y

With Super Resolution –

Real measured values are captured

This is not an interpolation process

Super Resolution : Super Sampling & DeconvolutionDeconvolution

Super samoling provides multiple pictures, slightly shifted

Deconvolution can reduce the blur, images are sharper & more detailed

Required –

Some arbitrary motion provided by user

A smart algorithm provided by testo

testo Solution : Combine super sampling & deconvolution

Advantages

Advantages of Super Resolution:

•Improves the image quality of your thermal imager by one class

•More correct temperature information on small objects

•Improves the geometric resolution (IFOV) of the thermal imager by factor 1,6 which helps to detect temperature variation in smaller objectsp j

•Provides more details for the analysis

•Better image quality for your report
