. Description only, reasonable animations. Considers the case of two nearby
beam splitters

Shows a working device. Confocal
optical cavity
, one of the mirrors scans back and forward moved by a
piezoelectric motor
, this is called a "scanning Fabry-Perot interferometer".
Does not produce an interference pattern, only an on/off blob, which is then fed into an
oscilloscope
for analysis. The oscilloscope shows both the mirror displacement (which is given by a voltage) and the light detector output.
