After years of anticipation, AR glasses are finally reaching a pivotal point. As hardware design evolves to deliver lighter, slimmer, and more comfortable devices, we are on the cusp of making AR truly wearable for everyday life. This breakthrough is driven by the convergence of miniaturized components and scalable manufacturing that enable brands to develop […]

Galvanometer scanner and optical errors. The galvanometer scanner, while incredibly fast and agile, brings its own set of errors. F-theta lenses, which are used to translate the scanner’s angular motion into a flat focal plane, are not perfect and introduce spatial nonlinearities known as pincushion or barrel distortion (see Fig. 3). Furthermore, the laser beam

New solutions for process monitoring As the demand for precision and efficiency in laser processing grows, manufacturers struggle to maintain quality assurance with outdated methods. Manual inspections and conventional monitoring systems often lead to high error rates, increased scrap, production downtimes, and inefficient workflows. Common production challenges include unstable processes, high scrap rates, undetected process

Prototype quantum networks, pluggable fiber-optic quantum comms modules ahead Photon pairs produced by the group’s devices are ready to build prototype quantum networks for distributing quantum information. “We use a 1550-nm wavelength compatible with existing long-haul fiber infrastructure, and Professor Kumar’s group at Northwestern recently showed that quantum and classical signals can coexist on the
