Researchers have developed a compact and lightweight single-photon airborne lidar system that can acquire high-resolution 3D images with ... photon avalanche diode (SPAD) arrays.

‘Revolutionizing the SLM process’ Dr. Richard Taylor, CTO at Vector Photonics, commented, “3D metal laser printers hold metal powder in a powder bed at just below its melting point. Currently, CO 2 or ...

What are optical phased arrays ... in a future integral 3D display. Such a display will reproduce spatial images via time-division display by high-speed optical beam scanning, as shown in Fig.
