Procedure for imaging of increment cores in a typical sample holder: the laser sensor measures the heights across line 1 and 2 (top) and based on the peaks (bottom, only the results of line 1 are shown) the blue lines (top) are defined along which the laser sensor measures detailed heights to inform the camera the number of images to take at each position
