A new testing system measures system voltage as a function of light intensity in outdoor setting, enabling real-time performance measurement and diagnostics.

Fiber optic sensors - used in critical applications like detecting fires in tunnels, pinpointing leaks in pipelines and predicting landslides - are about to get even faster and more accurate.

A new device can overcome challenges like bad weather to deliver more secure, reliable communications. This could aid military communications in challenging areas, improve the ability of self-driving cars to see the environment around them and speed up wireless data for potential 6G networks.
