NASA Turns to Laser Communications System for Data Transfer Boost
This summer, NASA will launch its Laser Communications Relay Demonstration (LCRD), setting the stage for high-speed transmission of data between planets. NASA missions have been using the same technology — radio frequency communications — since the 1950s and the beginning of spaceflight.

Adaptive Optics Keep an Eye on Space Junk
Researchers at Australian National University (ANU) have employed an artificial guide star to bring objects orbiting Earth into focus. The approach may help mitigate risks from space debris. The guide star laser is a tool in adaptive optics, a field that eliminates the haziness caused by turbulence in the atmosphere.

Optical Fiber-Based Probe Enables Phonon Imaging in 3D
A University of Nottingham research team has developed a phonon probe device that can simultaneously access 3D spatial information and mechanical properties from microscopic objects. The probe operates at the GHz range, at which the wavelength of sound becomes comparable to ultraviolet optical wavelengths, providing opportunity for high-resolution imaging.

Freeform Optics for Imaging: Mid-Spatial Frequency Errors
Wed, Jun 2, 2021 1:00 PM - 2:00 PM EDT
Residual mid-spatial frequency (MSF) surface errors are common byproducts of the computer-controlled sub-aperture manufacturing techniques needed for fabrication of freeform optics. In this presentation, Thomas Suleski, Ph.D., provides an overview of MSF surface error signatures, specification methods, and performance impacts. Part 3 of the 2021 Freeform Optics Series.

Polarization Extinction Ratio Measurement in Highly Birefringent Materials: Challenges and Solutions
Wed, Jun 23, 2021 1:00 PM - 2:00 PM EDT
This webinar with Wajih Daab, product line manager for Luna Innovations, discusses the Polarization Extinction Ratio (PER) testing solutions offered by Luna which help manufacturers accelerate the testing time and improve measurement accuracy. Presented by Luna Innovations, Inc.

.: All Things Photonics

Bishnu Pal, author of "Frontiers in Guided Wave Optics and Optoelectronics" and dean of academics at Mahindra University's Ecole Centrale School of Engineering, is our guest. From his start in semiconductor physics to numerous collaborations in the areas of fiber optics, silicon photonics, specialty fibers, and optical materials, Pal walks us through his journey in optics and photonics, which earlier this year saw him recognized with the SPIE Maria J. Yzuel Educator Award in recognition of four decades of educational leadership and sustained contributions in the field.
