Some motion sensors are based on optical measurement technologies to provide accurate velocity and position measurements without requiring physical contact with the object or surface being monitored.

Unlike gravitational wave detectors, we used a triangular optical cavity, not a linear optical cavity in order to decrease the noise level of the displacement sensor and maintain stable operation of ...

Chicago, Jan. 29, 2026 (GLOBE NEWSWIRE) -- The global displacement sensors (non-contact) market was valued at 9,017.18 million in 2022 and is expected to reach US$ 13,743.53 million by 2031, growing ...

Sensors for the measurement of displacement based on a number of different physical principles are available for a wide range of applications. This article considers systems capable of resolutions of ...

SICK, one of the world’s leading manufacturers of sensors, safety systems, machine vision, encoders and automatic identification solutions for factory and logistics automation, announced the launch of ...

Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...

Jaguar Cars are using a new long distance sensor to measure impact speed in pedestrian crash simulations at their engineering centre in Coventry. The Micro-Epsilon laser triangulation sensor promises ...

One of the most unknown phenomena in modern physics is gravity. Its measurement and laws remain somewhat of an enigma. Researchers at Tohoku University have revealed important information about a new ...
