In the face of the need to set international standards for the use of quantum technologies in science and industry, a consortium formed by 14 organizations from 6 countries, led by the Hudson Institute based in Washington, D.C., has prepared two recommendations.
Researchers from MIT and elsewhere have recorded, for the first time, the “temporal coherence” of a graphene qubit — meaning how long it can maintain a special state that allows it to represent two logical states simultaneously.
The sensor is made up of a series of gold disk-shaped nanoparticles on a glass slide. The team at Bath discovered that when they shone an infra-red laser at a precise arrangement of the particles, they started to emit unusual amounts of ultra violet (UV) light.
UNSW scientists have shown that their pioneering single atom technology can be adapted to building 3D silicon quantum chips – with precise interlayer alignment and highly accurate measurement of spin states.
First Sensor develops reliable sensor solutions for detecting light, pressure, level, radiation, flow, and acceleration.
Automotive journalist, Alex Roy, talks about thermal cameras in autonomous driving with Stuart Klapper from Veoneer and Paul Clayton from FLIR Systems.
Measuring very low power beams of light can be tricky; even small values of noise, drift or offset can have major impact on your readings. In this video, we’ll look at some best practices that can help you get the best performance from your very low power measurements.
Scanning slit profilers can make very accurate measurements of beam diameters as small as 5 microns, while cameras are limited to beams greater than 45 microns. This makes applications for focusing lasers or building optical systems much easier with a NanoScan. This video explains how to choose the right NanoScan for your application.
This video introduces First Sensor’s core competencies available from design concept to production.
This eBook addresses the inherent heating problems in electrical system designs as they become smaller and more powerful. Whether it is in the early rapid prototyping design phase, failure analysis and quality assurance phase, or troubleshooting on product returns, thermal measurement is a key tool for identifying problems and improving thermal management solutions. The FLIR eBook also offers insight and advice from industry experts on new infrared technologies, innovations, and techniques. Read more.

Optical filters are used in many applications and the surface figure and wavefront distortion requirements of filters are dependent on where and how they are used. If filters are only used in sensing applications with very tolerant detector geometries, there may be no need, in practice, to put any constraints on the surface figure or wavefront distortion. This white paper helps the reader understand where, when, how, and how much to specify wavefront distortion to ensure that functional requirements of filters are guaranteed while unnecessary and costly constraints are avoided.
Rather than radio waves, most LiDAR systems use infrared lasers, particularly diode lasers. The limiting factor on a diode laser’s pulse features is not the laser itself — it is the electrical driver that supplies the electrons to the laser diode. This paper discusses challenges involved in optimizing nanosecond electrical driver performance in a flash LiDAR system.
New infrared camera cores with high operating temperatures allow the construction of imaging systems that are smaller, lighter, and less power-hungry. That’s opening up new uses, from airborne to hand-carried applications.
Deep learning is set to alter the machine vision landscape, enabling new applications and disrupting established markets. It’s never been easier to get started, but where do you begin? This article provides an easy-to-follow guide to building a deep learning inference system for less than $1000.
LASER COMPONENTS USA, a specialized provider of laser and optoelectronic components in the US and Canada, is proud to present the FLEXPOINT MVstereo laser module generating truly random patterns with 31,806 or 47,708 dots. These patterns are generated completely randomly; even in partial patterns, repetitions do not occur. The range of pseudo random patterns has also been expanded: Versions with 40,100 and 29,594 dots are now also available. Due to the different number of dots and the different fan angles of the patterns, the customer can choose the optimal optics for his application. Both versions are available with red (660 nm) or NIR (830 nm) lasers, and both are eye safe (laser class 1 and 1M).
Solar cells, quantum computing and photodynamic cancer therapy. These all involve molecules switching between magnetic and nonmagnetic forms. Previously this process, called a “spin flip,” was thought to occur slowly in most cases.
Insulators that are conducting at their edges hold promise for interesting technological applications. However, until now their characteristics have not been fully understood. Physicists at Goethe University have now modelled what are known as topological insulators with the help of ultracold quantum gases.
The company will premiere the second product in the family of narrow-spectral-output UVLED devices at Photonics West, Feb. 5 - 7, 2019, in Opto Diode’s booth #4539, Moscone Center, San Francisco.
