Abstract

This report describes a set of waveforms for verification purposes and other calculations relating to temporal light modulation (TLM). The waveforms are intended to be used in comparisons of software implementations and for estimating measurement uncertainty from modelled effects as well as other calculation-based studies of TLM. The report gives TLM metric values of PstLM and SVM, these are calculated from various implementations of the TLM metric algorithms. The results show standard deviations, all under 0.04 for both metrics, except one outlier. Furthermore, the report gives examples of how estimation of measurement uncertainty can be derived from applying various effects that can be modelled and applied to the waveforms. This is used to study the effect on the resulting metrics. Specific guidance is given towards using the examples to reach measurement uncertainties under 0.05 for both PstLM and SVM. The waveforms are stored in a permanent repository, for referencing and comparing results across platforms. This report is part of the output from the EMPIR project MetTLM Metrology of Temporal Light Modulation (20NRM01). For more information see the project website mettlm.eu.
