Researchers at the University of California, Los Angeles (UCLA) have developed an optical computing framework that performs large-scale nonlinear computations using linear materials. Reported in ...

Researchers report that they have invented new nanoscale sensors of force. They are luminescent nanocrystals that can change intensity and/or color when you push or pull on them. These 'all-optical' ...

There’s apparently little limit to the innovative ways that are available to sense temperature, among the most widely sensed physical parameters. Now, a team Washington University in St. Louis has ...

For electrical engineers working in almost any part of the wired or wireless spectrum, the spectrum analyzer is a critical test and measurement tool. For optical engineering, the equivalent tool is ...

The Optipact motion sensors determine rotational or translational velocities of machinery or products in a wide variety of applications. The sensors are built around an optical system: The velocity of ...

Soil is often perceived simply as "dirt," but in reality, it is a dynamic, living system that acts as Earth's natural sponge. Unfortunately, common agricultural practices—including deep plowing and ...

The evolution of modern healthcare has been profoundly shaped by advancements in medical devices, with sensors playing a crucial role in this transformation. As the demand for more accurate, portable, ...

Air bubble sensors are used to detect air or gas bubbles in flexible clear plastic tubes. They are intended to prevent air infusions. The air bubble sensor has no contact with the liquid and is ...

A new technical paper titled “Massively parallel and universal approximation of nonlinear functions using diffractive processors” was published by researchers at UCLA. “Nonlinear computation is ...
