New Red Phosphor Could Make LEDs More Energy-Efficient
A team at the University of Innsbruck, in cooperation with OSRAM Opto Semiconductors, has synthesized a new high-performing red phosphor for LEDs that could make LED lighting more energy-efficient. The new phosphor, called SALON by the researchers, has slightly shifted the light emission from red toward blue.

Optically Invisible Antennas Could Empower 5G Devices
Researchers at Pohang University of Science & Technology (POSTECH) developed a way to build optically invisible antennas that could be embedded within superresolution displays. The Antenna-on-Display (AoD) technology could provide an alternative to conventional antenna technology for 5G devices.

Canon Surface Reflectance Analyzer
Canon U.S.A. Inc., Industrial Products Div.
Canon RA-532H, Surface Reflectance Analyzer (goniophotometer), is a compact, portable device capable of measuring 4 surface appearance conditions in a single pass: gloss, haze, image clarity (IC), and BRDF (Bidirectional Reflectance Distribution Function). Additionally, Canon has recently released its own new parameter, “Scattering” parameter, overcoming the shortage of both IC and DOI (Distinctiveness of Image) when evaluating matte and textured surfaces as well as orange peel surface.

Study of Laser/Plasma Interactions Moves Forward with Scalable 3D Simulation Tool
Researchers from Lawrence Berkeley National Laboratory (Berkeley Lab) and CEA Saclay simulated laser/plasma coupling mechanisms using a new 3D particle-in-cell simulation tool. A more detailed understanding of laser-plasma interactions could contribute to the development of novel particle and light sources for application in medicine, industry, and fundamental science.

OSA Digital Holography & 3D Imaging 2019
May 19-23, 2019 - Bourdeaux France
The Digital Holography and Three-Dimensional Imaging meeting will provide a forum for learning about digital holographic, 3D imaging, and display methods. The conference will cover interferometry, phase microscopy, novel holographic processes, 3D and novel displays, integral imaging, computer-generated holograms, compressive holography, full-field tomography, specific image and signal processing, and holography with various light sources including coherent to incoherent and X-ray to terahertz waves. This will be an interdisciplinary conference with a broad field of applications in biomedicine, biophotonics, nanomaterials, nanophotonics, and scientific and industrial metrologies.

Spectroscopic OCT: Seeing Under the Skin with Depth-Resolved Spectroscopy
Tue, May 14, 2019 1:00 PM - 2:00 PM EDT
This webinar, presented by Adam Wax, Ph.D., will introduce new methods for evaluating skin injury using spectroscopic measurements based on coherence imaging. These methods were developed by Wax and his group at the Biomedical Interferometry, Optics and Spectroscopy (BIOS) lab at Duke University. Wax will discuss spectroscopic OCT (SOCT), an extension of OCT technology for analyzing structural as well as spectroscopic information. He will present his lab’s application of SOCT for burn injuries and also address SOCT’s potential in the area of cancer detection.
