Claim 11:
12. A THz measuring device for measuring a measurement object, the THz measuring device comprising:
a THz transceiver for emitting THz radiation along an optical axis and receiving reflected THz radiation,
a controller device for collecting measurement signals of the THz transceiver and determining a distance and a measurement result of the measurement object, and
an output device for putting out a measurement result,
wherein the THz measuring device is portable and comprises a grip region for being grabbed and handled by a user, the controller device being configured for a phase of pre-measurement and a phase of main measurement,
the controller device being configured to emit, in the phase of main measurement a main measurement THz transmission beam having a main measurement bandwidth along the optical axis,
the controller device determining in the pre-measurement whether a measurement object has been detected and, if the measurement object has been detected, determining the distance of the THz measuring devices or the THz transceiver from a boundary surface of the measurement object and
comparing the same with a distance limit and, depending on the comparison, initiates or indicates the main measurement when the distance limit has not been exceeded, and
the controller device being configured to determine measurement characteristics of the measurement object in the main measurement
wherein the THz measuring device is configured to emit, in phase of pre-measurement, the THz radiation as a first THz transmission beam along the optical axis having a first bandwidth, and, in the phase of main measurement to emit the main measurement THz transmission beam as a second THz transmission beam having the main measurement bandwidth along the optical axis,
the main measurement bandwidth being wider than the first bandwidth, for a higher resolution.
