Optical Imager Poised to Improve Diagnosis and Treatment of Dry Eye Disease
Researchers have developed a new non-invasive optical imaging system that promises to improve diagnosis and treatments for dry eye disease. Dry eye, which often causes irritation and blurred vision, occurs when there is instability in the inner layer of the tear film that protects the outside of the eye.

Tunable Optical Chip Paves Way for New Quantum Devices
Researchers have created a silicon carbide (SiC) photonic integrated chip that can be thermally tuned by applying an electric signal. The approach could one day be used to create a large range of reconfigurable devices such as phase-shifters and tunable optical couplers needed for networking applications and quantum information processing.

New Chip Poised to Enable Hand-Held Microwave Imaging
Researchers have developed a new microwave imager chip that could one day enable low-cost handheld microwave imagers, or cameras. Because microwaves can travel through certain opaque objects, the new imagers could be useful for imaging through walls or detecting tumors through tissue in the body.

Laser-Based System Detects Fires Even in Dusty, Harsh Environments
Researchers have developed a new laser-based system that offers an efficient and low-cost way to detect fires in challenging environments such as industrial facilities or large construction sites. With further development, the system could eventually detect fires that are more than a kilometer away.

Record-Fast Neutron Tomography Tracks Water Pathways into Plants
For the first time, researchers have captured neutron tomography images in about a second, nearly an order of magnitude faster than previously reported attempts. Until recently, long image acquisition times have been the major obstacle to using this non-invasive technique to study dynamic 3D processes such as the water exchange between roots and soil.

Laser Prototype for Space-Based Gravitational Wave Detector
Researchers have announced a prototype for a laser at the heart of the first space-based gravitational wave observatory, known as the Laser Interferometer Space Antenna (LISA) mission. The team’s new laser nearly meets the stringent requirements outlined for LISA’s instrumentation, representing an important step toward bringing the ambitious observatory program to fruition.
