    Abstract: An apparatus determines a layer thickness of a plurality of layers arranged on a body. The apparatus includes a THz transmitter configured to emit a THz signal to said plurality of layers and a THz receiver configured to receive a reflected portion of said THz signal that has been reflected by at least one layer of said plurality of layers. The apparatus is configured to determine the layer thickness of at least one of said plurality of layers based on said reflected portion of said THz signal. The apparatus further includes a distance measuring device for determining at least one parameter characterizing a distance between said apparatus and said body, wherein said distance measuring device may include at least one optical triangulation sensor.

    Abstract: A measuring device comprises a Terahertz, THz, transmitter configured to emit a THz signal to an object to be measured and a THz receiver configured to receive a reflected portion of said THz signal that has been reflected by said object. The said THz transmitter and said THz receiver are arranged in a measuring head of said measuring device. The measuring device may vary a distance between said measuring head and said object to be measured, emit, by means of said THz transmitter, said THz signal to said object to be measured, receive said reflected portion of said THz signal, and determine a first parameter characterizing a detected signal proportional and/or related to said received reflected portion of said THz signal.
