Its more advanced version, which allows recording and subsequent reconstruction of up to three sets of data using just one data object-A complex interferogram-was developed in the past and became known as complex interferometry. Employing this diagnostics, not only the usual phase shift, but also the amplitude of the probing beam as well as the fringe contrast (leading directly to the phase shift time derivative) can be reconstructed simultaneously from such a complex interferogram. In this paper it will be demonstrated that even in the case of a not particularly good diagnostic beam quality these three quantities can be reconstructed with a high degree of accuracy provided both the diagnostic beam as well as the corresponding optical line feature a reasonable stability. Such stability requirement is important as all together four shots need to be recorded: the signal complex interferogram, the reference interferogram as well as the intensity structures of the signal and reference part of the diagnostic beam.
