From IR to THz, Space Telescopes Get Detector Array Upgrades August 25 marked the Spitzer Space Telescope’s “sweet 16.” Launched in 2003 with a planned primary mission of 2.5 to 5 years, the infrared observatory — the last of NASA’s Great Observatories to take flight — far outlasted its initial mandate, depleting its store of liquid helium coolant and transitioning into a “warm mission” in 2009. In their...
Motion Control Solutions for High-Precision, Large-Field Laser Micromachining High-precision, high-throughput laser micromachining typically requires galvo scan heads with a short focal length, which in turn produces a small image field, or field of view (FOV). However, a...
High-Speed 3D Inspection with Liquid Lenses The concept of liquid lenses, which involves controlling the shape of a liquid to alter the properties of a lens, is not new. The human eye uses this concept every day as it focuses on objects near...

Dream in a bottle 10th February 1989 Dear Amy, I must write a special letter and thank you for the dream in a bottle. You are the first person in the world who has sent me one of these and it intrigued me very much. I also liked the dream. Tonight I shall go down to the village and blow it through the window of some sleeping child and see if it works. With love from, Roald Dahl Shaun Usher, the curator of the...
Lidar Special Section
Lidar and Optical V2V: On the Road to Autonomous Vehicles Two different optical technologies — one already deployed, the other still on the drawing board — promise to ease autonomous vehicle integration. Lidar, the optical analog to radar, is deployed in Waymo and Uber vehicles and acts as the eyes, helping autonomous processors “see” the surrounding environment. Optical vehicle-to-vehicle (OV2V) communication is still in the design phase and can...

Sensor Detects Buried Objects from Moving Vehicle A new laser-based sensor, developed by a team at the University of Mississippi, can detect buried objects such as land mines even while the detector is in motion. The new device, called a Laser Multi Beam Differential Interferometric Sensor (LAMBDIS), provides detection capabilities comparable to laser Doppler vibrometers (LDVs), but is less sensitive to motion, allowing it to be used aboard a...
