CAPTURE OF THERMAL IMAGES OF AN OBJECT

摘要

The invention relates to an apparatus and a method for capturing thermal images of an object (1). The apparatus has: an excitation unit (2) for mechanically exciting the object (1) with a periodic excitation signal, a camera (3) for capturing the thermal images of the object, wherein a thermal image has a plurality of pixels, wherein a pixel is respectively intended to represent a heat signal (8) acquired from the object (1), and means (4) for matching the capture of the thermal images of the object (1) and the periodic excitation signal in such a manner that thermal images captured in a plurality of periods of the periodic excitation signal can be used to determine information relating to the heat signals (8) respectively represented by the pixels during a period.
