Fig. 13

A schematic of the TEM setup for CACTI. After the beam passes through, the sample portions of it are occluded by the aperture. The occluded images are integrated together on the camera. Because each image has a different encoding, defined by the position of the aperture, they can be recovered by CS inversion. In order for each image to get a different encoding, the piezoelectric stage is driven by the function generator at a rate faster than the camera
