Stanford University researchers have developed a laser-based system that can reproduce images of objects hidden from view. The technology can be used to enhance the safety of self-driving vehicles, as well as applied to serve other functions.
Scientists at Rice University and the Indian Institute of Science, Bangalore, have discovered a method to make atomically flat gallium that shows promise for nanoscale electronics.
A large team of Russian researchers from Rosatom, joined by three MIPT physicists, has modeled the impact of a nuclear explosion on an Earth-threatening asteroid. They manufactured miniature asteroids and blasted them with a laser.
An international team of quantum scientists and engineers led by the University of Bristol and involving groups from China, Denmark, Spain, Germany and Poland, have realised an advanced large-scale silicon quantum photonic device that can entangle photons to incredible levels of precision.

Fizeau interferometers are used to measure the shape and quality of optical surfaces with high precision by comparing the optic under test to a reference optic. However, it is important to remember that not all reference optics are created equal, as design and construction may cause quality fluctuation. When using reference optics to assess the quality of other optical surfaces, it is essential to have confidence in the quality and precision of the reference optics.
In metrology and process control, precision is the name of the game. Vision software must be able to identify all dimensions presented and have the ability to auto adjust the alignment accordingly. ZYGO recognized that and sought to make the process simpler for all involved. Because of this, ZYGO's Mx™ software can be fully integrated with Cognex VisionPro® across the full optical profiler and laser interferometer product lines.
There are many solutions available that attempt to correct a poor environment in order to mitigate its undesirable effects. A typical solution is to use a vibration isolation table, and sometimes facilities are completely renovated in order to establish a "metrology" grade environment. These solutions are expensive, and even cost-prohibitive for some operations, leading ZYGO engineers to come up with an innovative solution – QPSI™ technology.
The “car of the future” isn’t about driving, but relaxing. Driverless cars will employ functional and accent lighting that allows passengers to just enjoy the ride. Installed smart systems that can imitate natural light will adjust their color and warmth automatically, depending on the time of day, much like some airlines do. This article dives into the importance of lighting in the future of autonomous driving, and discuss how designers and engineers are rethinking light for car interiors.

A new tunnel complex carrying high voltage power lines under the Thames in East London will help supply the city’s growing demand for electricity. Built for UK Power Networks and carrying 132,000 volt cables, the tunnels will bring an extra 400 megawatts of electricity into the capital.
Diffractive optical elements (DOEs) allow laser beams to be split, bundled, or formed into almost any shape and are used in multiple applications. The food industry, for instance, uses them for laser perforation, when it comes to applying micro holes into packaging for fruit or vegetables. These allow the food to “breathe” and thus extend its storage life. The holes have diameters of between 50 μm and 300 μm depending on the type of food and material.
A simple potassium solution could boost the efficiency of next-generation solar cells, by enabling them to convert more sunlight into electricity.
Researchers from the Moscow Institute of Physics and Technology have “rediscovered” a material that can lay the foundation for ultrahigh-speed quantum internet.
The world’s first continuous room-temperature solid-state maser has been developed by UCL and Imperial College London scientists.
