The structure and operating principle of a laser flat scanning system for the engineering machinery are described in the paper.

Now, while the rest of the group walked up a gully scanning for fossils, Berhane Asfaw and I headed down onto the flat plain to the spot where the skull had been found.

However under the unconventional CT scanning mode, using the low-energy X-ray source, which can save the energy, can fulfill the CT reconfiguration of the specimens with the flat-type.
