Cited passages: §4.1 and Figure 1: source, splitter, mirrors and detector; §§5.1–5.3: hardware, manual micrometer, near/far alignment, fringe patterns and live voltage or oscilloscope readout; §§6.1–6.4: angular mismatch, splitter ratio, polarization controls and noise estimates. The guide gives a protocol, rather than a published measured dataset.
