A Fourier Transform is applied to the coherent detection signal in the THz photomixer arrangement. The method is used in measurements of a refractive index of plastic materials.
In the paper, Fourier transform has been used for calculations of a refractive index of dielectric samples measured in the terahertz photomixer arrangement. We considered measurement limitations caused by a sampling frequency and a photomixer bandwidth.
In this paper, interference aspects of terahertz transmission are considered. Possible interference effects in indoor THz communication are experimentally proved using a THz photomixer setup. The method of coherent homodyne detection is applied to explain the problem. Fourier Transform is used for precise analysis of the interference effects and… (More)
