Researchers have shown that a quantum-inspired technique can be used to perform LiDAR imaging with a much higher depth resolution than is possible with conventional approaches. LiDAR, which uses laser pulses to acquire 3D information about a scene or object, is usually best suited for imaging large objects such as topographical features or built structures due to its limited depth resolution. In Optics Express, Lyons and first author Robbie Murray describe the new technique, which they call imaging two-photon interference LiDAR. They show that it can distinguish reflective surfaces less than 2 millimeters apart and create high-resolution 3D images with micron-scale resolution.
