From: Phase-sensitive interferometry of decorrelated speckle patterns
Phase differences between the ends of the photoreceptor outer segment in the living human eye at different times compared to the initial phase at t = 0. The entire measurement ended at about t = 14.6 s after initiating a light stimulus. (a–g) Phase difference obtained by directly comparing to pre-stimulus phase with phase after different times. (h–n) Phase difference obtained from the cross-spectrum as described in the Methods section (by minimizing Eq. (14)). (o–u) Speckle pattern of one of the involved layers before the stimulus and at the respective times. It can clearly be seen, that that the speckle pattern changes with time. Scale bars are 200 μm.
