New tests can hasten use of small precision devices in medicine, food safety, spacecraft.
Researchers at the National Institute of Standards and Technology (NIST) have published landmark test results that suggest a promising class of low power and small sized sensors can be used in high-radiation environments and to advance important medical, industrial and research applications.
Photonic sensors convey information with light instead of electric currents in wires. They can measure, transmit and manipulate streams of photons, typically through optical fibers, and are used to gauge pressure, temperature, distance, magnetic fields, environmental conditions and more.
