From IR to THz, Space Telescopes Get Detector Array Upgrades
Before it is decommissioned in January 2020, Spitzer will use its operational IR detector arrays to continue identifying objects for the James Webb Space Telescope to further investigate. Led by NASA and its European and Canadian space agency partners, this scientific successor to both the Spitzer Space Telescope and the Hubble Space Telescope is currently scheduled to launch in March 2021.

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 growing number of high-tech manufacturing areas, such as OLED display fabrication, require the processing of workpieces larger than can fit into these reduced image fields, while simultaneously requiring a high level of accuracy and throughput.

High-Speed 3D Inspection with Liquid Lenses
The ability to control the focal length of a lens at ultrahigh speeds in the focal range required by an application is tremendously valuable. Many scientific, industrial, and commercial applications demand fast modulation and control over the focus of the lens to enable high-speed illumination and measurements. For example, in noncontact inspection systems, the traditional approach requires mechanically moving the lens assembly to measure the sample along its height. However, this is often one of the bottlenecks that affect the speed of measurement and the overall inspection throughput.

Structured Light Could Be Route to Higher Information Capacity per Photon
Researchers from the University of Witswatersrand (Wits) have reported on progress made in the use of structured light in quantum protocols to create a larger encoding alphabet.
The researchers said that since patterns of light can be distinguished from each other, they can be used as a form of alphabet. “Light comes in a variety of patterns that can be made unique — like our faces,” professor Andrew Forbes said. “There are, in principle at least, an infinite set of patterns, so an infinite alphabet is available.”

A prototype of a large-scale quantum processor made of laser light has been created by a team from Australia, Japan, and the U.S. The processor has built-in scalability that allows the number of quantum components to scale to extreme numbers.

Scientists at the Vienna University of Technology have uncovered the source of a special type of quantum light created at certain points in the 2D material tungsten diselenide (WSe2) when it is supplied with energy. They found that this special-nature light, which exhibits an antibunching effect, results from the interaction between single atomic defects in the material and mechanical strain. Computer simulations showed how electrons were driven to specific places in the WSe2, where they were captured by a defect, lost energy, and emitted a photon.

Frequency-Domain Fluorescence Lifetime Imaging System Improvements and Applications
Wed, Nov 20, 2019 10:00 AM - 11:00 AM EST
Since its introduction in 2014, the FD-FLIM pco.flim camera system has been applied to many different areas, from FRET to endogenous fluorescence, from oxygen to pH measurement, from large technical applications to light-sheet microscopy. In this webinar presented by PCO, Gerhard Holst will demonstrate and discuss improvements in the use and applicability of the pco.flim camera. New results including investigation of microplastics on lab filters, pH measurements, oxygen measurements in a marine environment, assistance for neurosurgery, and rapid FD-FLIM measurements will be shown to demonstrate the flexibility of the pco.flim camera system.
