    Chlorophyll fl uorescence is a powerful optical reporter signal yielding information about modulation of light use effi ciency. In standard imaging applications, fl uorescence transients are captured in 2 spatial dimensions and in time. Here, we demonstrate that it is possible to combine the information obtained in the 2D-t format with the 3D reconstruction of the entire plant using a process called co-registration. Two diff erent approaches to co-registration are presented here. Th e fi rst one is based on an image registration method, where the precise transformation parameters are iteratively estimated. Th is approach assumes that the initial position of a scanner is known and thus makes the method less general. To remove this assumption, a second approach can be used, which is based on analysis of a known calibration object. Th ere is no need to re-calibrate the system between individual measurements.
