Abstract: In the measuring device and measuring method, confocal measuring principle is utilized. A certain component of an optical measurement signal is, from the point of view of both illumination and imaging, in focus only at one point on the virtual measuring surface. In the measuring device, the surface to be measured always hits a common focus point of the illumination and imaging, whereby a reflection is generated. The reflected optical signal is directed to a detector belonging to the imaging unit, where one picture element of the detector corresponds to a certain focus point, respectively. The optical efficiency received by each picture element is indicated. The light reflecting from the intersection of the virtual measuring surface and the surface of the object produces an intensity maximum for the detector. This maximum point is indicated and converted in the imaging unit (13) into the height of the surface of the object.

Abstract: A measuring apparatus (200) is provided for inspecting a seal (50) of an item (20). The measuring apparatus (200) includes a radiation source (510, 520) for providing radiation for illuminating the seal (50) of the item (20), a detector (530, 540) for receiving radiation from the item (20) for generating a corresponding detected signal, and a processing arrangement (160) for processing the detected signal to generate an output signal indicative of a state of the seal (50). The radiation source (510, 520) is arranged to focus the radiation into a plurality of focal points at the seal (50) of the item (20), wherein the focal points are mutually spatially spaced apart. Moreover, the detector (530, 540) is arranged to image one or more of the focal points and to be selectively sensitive to an intensity of radiation received from the one or more focal points to generate a detected signal. Furthermore, the measuring apparatus (200) includes a processing arrangement (160) for receiving the detected signal and for processing the detected signal to generate the output signal indicative of the state of the seal (50).
