"high depth resolution two-photon interference LiDAR... two reflective surfaces of a piece of glass about 2 millimeters thick. Traditional LiDAR wouldn't be able to distinguish these two surfaces, but the researchers were able to clearly measure the two surfaces. They also used the new method to create a detailed 3D map of a 20-pence coin with 7-micron depth resolution... method could capture the level of detail necessary to differentiate key facial features or other differences between people"
