Abstract
A complex-valued transmission matrix describing a scattering medium can be
constructed from a sequence of many interferometric measurements. A major challenge in such
experiments is to correct for rapid phase drift of the optical system during the data acquisition
process, especially when the phase drifts significantly between consecutive measurements.
Therefore, a new method is presented whereby the exact phase drift between two measurements
is characterised and corrected for using a single additional measurement. This approach removes
the need to continuously track the phase and significantly relaxes the phase stability requirements
of the interferometer, allowing transmission matrices to be constructed in the presence of fast
and erratic phase drift.
