They measure the distance between the sensor and a target surface without physical contact, using a laser beam. Designed for high-speed, non-contact operation, the sensors are designed to measure ...

For the first time, researchers have used high ... laser wavelength and the optical system's ability to focus the laser beam.

Lithium-sulfur batteries are expected to supersede existing lithium-ion batteries due to sulfur cathodes' high ... speed can achieve about 2 cm2/minute using only a single beam laser.
