Biological Systems Inspire New Image Preprocessing Solutions
Data, as the saying goes, is king. But as any chess player knows, the king without his minions is hamstrung by limited mobility. The ubiquitous deployment of CMOS and CCD imagers across a range of industries and applications has generated an avalanche of image data. However, without the use of centralized processing units — a CPU, GPU, or cloud processor — that data is similarly hobbled.

How Vision Systems Can Deliver More than the Sum of Their Parts
The use of both 3D-imaging technology and smart cameras is expanding the flexibility and capabilities of machine vision systems. Integrating these elements with advanced image preprocessing and intelligent software can further enable automated inspection applications that were once challenging or impossible to automate.

Drones Deliver a Fresh Take on Airborne Imaging Applications
Initially swooping in to provide aerial shots in big-budget movies, unmanned aerial vehicles — or drones, in consumer parlance — are now bringing aerial cinematography technology to other applications. Drone-mounted imagers are helping to inspect infrastructure, monitor crops, and conduct search and rescue operations. They could eventually deliver vital goods. As demand grows for these high-flying imaging platforms, the technology is evolving to allow drones to perform finer maneuvers, capture higher-quality images, and stay airborne longer.

Nonlinear Multimode Waveguide for Flip-Flopping Azimuthons Demonstrated
A research team from Xi’an Jiaotong University has demonstrated weakly nonlinear waveguides that guarantee the stable propagation of vortex beams known as azimuthons. The research may have applications in encoding and encrypting optical information. Azimuthons carry an orbital angular momentum and can now be made to exhibit a mutual conversion pattern known as Rabi oscillation — a periodic motion between two different energy levels in the presence of an oscillatory driving field.

Responsive Photonic Biobased Materials Self-Assemble in Liquid Marbles

By coating droplets of an aqueous solution of hydroxopropyl cellulose with silica nanoparticles, and placing these “liquid marbles” inside an organic solvent, scientists have successfully made and displayed structural colors from cellulose-based polymers. Liquid marbles, which are millimeter-size droplets of liquid crystalline solutions, serve as a surrounding fluid in the system, and are coated to prevent them from mixing with the solvent.

Ashkin-Inspired Technique Enhances Laser Resonance

Technion-Israel Institute of Technology researchers have introduced a laser-resonator design inspired by the work of Arthur Ashkin. Created by graduate student Jacob Kher-Alden under the supervision of Tal Carmon, associate professor and head of the Optomechanics Center at Technion, the floating resonator design achieved 10 million circulations of light.

.: Upcoming Webinars

Focus on Recovering Signals in Optical Experiments
Thu, Oct 22, 2020 11:00 AM - 12:00 PM EDT
Capturing meaningful information while avoiding sizable overheads is crucial for all experiments in optics. In this webinar, Claudius Riek, Ph.D., of Zurich Instruments will look into the effect that specific settings for spectroscopy instruments have on the measurement results, focusing on: filter function, filter order and time constant. He will then explore the relevance of typical properties of electronic measurement devices for optical experiments such as dynamic range, measurement bandwidth and signal input noise. Presented by Zurich Instruments.

Dynamic Error Reduction via Galvo Compensation
Wed, Oct 28, 2020 1:00 PM - 2:00 PM EDT
This webinar with Scott Schmidt of Aerotech, Inc. will cover problems that arise in fixed-beam positioning (i.e., moving load) where the large moving mass of a system becomes a difficult problem to solve and address how these challenges may be overcome with hybrid stage-scanner system architectures. Analysis of overall/systemic errors will also be presented. Presented by Aerotech, Inc.
