Housing for glossmeter

A device for the non-destructive probing of a sample by means of electromagnetic wave reflection includes a metal body as part of its frame. The metal body forms a lateral wall and a separating wall enclosing an interior space. On a first side of the metal body, a shielding structure forms a plurality of shielded chambers for receiving RF circuitry. Interior space faces the second side of the metal body. A first circuit board containing driver and receiver circuitry is mounted to the first side of the metal body, and a second circuit board containing an antenna structure is mounted to the second side thereof.

Device for electromagnetically probing a sample

In order to accurately probe a structure of concrete, a series of probe signals with defined carrier frequencies are generated by a probe signal generator and coupled into the structure by an antenna. The returning echo signals are processed by an echo signal receiver. Processing includes phase and amplitude detection in a multiplier, frequency-specific scaling in a scaling unit, replacement of the measured phases and amplitudes in an interpolation unit, and the generation of time-domain data in a Fourier transformation module. The device is robust against RF noise, accurate and low-power.
