Two-Photon Microscopy Images (IMAGE) The Chinese University of Hong Kong Caption The researchers prepared two-photon microscopy images of a pollen grain by using (a) traditional point-scanning and (b) the new compressive imaging approach. The point-scanning imaging time was 2.2 seconds while the compressive imaging time required only 0.55 seconds.
