All-Optical Neural Network Uses Parallel Computation to Speed Problem-Solving
Researchers at The Hong Kong University of Science and Technology have demonstrated a multilayer all-optical artificial neural network. The researchers built and tested an all-optical neural network in which linear operations were programmed by spatial light modulators and Fourier lenses, while nonlinear optical activation functions were realized using laser-cooled atoms with electromagnetically induced transparency.

Welding with Pulsed Lasers Protects Temperature-Sensitive Materials
A new ceramic welding technology developed by engineers at the University of California, San Diego and the University of California, Riverside uses a series of short, ultrafast laser pulses to melt ceramic materials along the interface between two ceramic parts and fuse them together. Heat builds up only at the interface, so the melting is localized.

Quantum Entanglement Sent Over 50 Km of Optical Fiber
A team from the University of Innsbruck and the Institute of Quantum Optics and Quantum Information of the Austrian Academy of Sciences has achieved what could be a record for the transfer of quantum entanglement between matter (a trapped ion) and light (a photon).

Vutara Super-Resolution Microscopy
Bruker Nano Surfaces
Based on single-molecule localization techniques (PALM, STORM, etc.), Vutara 352 enables quantitative imaging at the nanoscale. With SRX software and its Quantitative Localization Microscopy (QLM) analysis suite, Vutara 352 can provide visual and quantitative information from biological samples. Frame rates up to 3000 fps allow data to be collected from live samples and perform time based measurements.

Intense Light Therapy Before Surgery Could Help Protect Heart
Researchers at the University of Colorado Anschutz Medical Campus have found that intense light amplifies a specific gene — Period 2 (PER2) — that makes the metabolism of mice and humans more oxygen-efficient. This amplification could offer protection against injury to the heart muscle if the light therapy were given before surgery.

Computational Imaging Tools Improve OCT Resolution in Lateral Direction
A new technique called optical coherence refraction tomography (OCRT) is able to increase the resolution of OCT down to a single micrometer in all directions, even in a living patient. The researchers combined OCT images acquired from multiple angles to extend the depth resolution to the lateral dimension.

Hands-On Digital Light: Spectral Design Tools for Human-Centric Lighting and Related Applications
Thu, Sep 12, 2019 10:00 AM - 11:00 AM EDT
This webinar will begin with a short review of the most promising spectral technologies and the current state-of-the-art. It will delve into the details of spectral design through a series of practical implementations, using one of the most versatile programming languages, Python (no previous knowledge is required, although it may be helpful). A link will be provided to a Python Jupyter Notebook so that you can follow and execute every line of code. You will learn how to calculate the spectral parameters of thousands of metamers through parallelization and vectorization, and build an optimized 24-hour circadian light sequence as a case study. The webinar will conclude with a recap that will put what you have learned into perspective and provide detailed guidelines on real-world implementations for a broad range of applications.
