Phase noise investigation in terahertz time-domain spectroscopy measurements
Abstract
We present a detailed study of the influence of time jitter in terahertz time-domain measurements. It proves to be particularly important in TDS based imaging measurements and can strongly influence the quality of the images.

In THz-TDS, various noise effects compromise signal quality; noise contributions include optical and electronic effects, laser intensity variations, and jitter noise.
“In THz-TDS, various noise effects compromise the signal quality [23 -25]. Noise contributions include optical and electronic effects [26, 27], laser intensity variations [28], and jitter noise [29, 30].”

Jitter noise has an equally significant impact on the attainable SNR level.
“In this section, we are going to discuss the effect of jitter noise, which has an equally significant impact on the attainable SNR level [25, 29, 32, 33].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
