CubeSats: Tiny Platforms for Orbiting Optics
Small, boxy satellites are ridesharing their way into outer space—and may lead to important advances in laser communications and cybersecurity.
by Patricia DaukantasNon-Line-of-Sight Imaging
Computational imaging techniques, sensitive photon detectors and considerable imagination are creating techniques for 3-D imaging of objects around corners and behind walls.

Animal Vision: Seeing Color
Color perception in animals has evolved to help in collecting information about the environment—from recognizing food sources to selecting mates. Many animals can perceive at least as many colors as humans and some even see into the ultraviolet. (For more on human color vision, see our feature “Color Vision and Color Spaces.”)
Setting America’s Quantum Course
A White House expert on quantum information science throws light on a recent strategic overview for the discipline—and on where U.S. quantum policy is heading.
Beyond the Visible
Raptor Photonics, a deceptively small U.K. engineering company, has been developing the next generation of short-wave infrared cameras.
Optics and Photonics Market Outlook 2019
Our columnist puts his finger on the optics industry’s pulse as a new year begins. The beat, he finds, is healthy and strong—but it bears some monitoring.
