Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, ...

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 ...

Optical techniques for high speed communications, computing and many types of data processing are increasingly well established. However, to be able to effectively employ photons in circuits and ...

The application of light for information processing opens up a multitude of possibilities. However, to be able to adequately use photons in circuits and sensors, materials need to have particular ...

Designed specifically for high-voltage sensing, a new generation of optically isolated amplifiers make monitoring and system protection circuits more accurate and easier to design. These iso-amps can ...

Using their Mosquito fabrication method, the researchers created a fan-out pattern of multiple thin light paths inside a thin sheet of PDMS. This created four optical channels that could be used for ...

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water. Researchers have developed a new optical sensor ...

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 ...

Marvell Technology (NASDAQ:MRVL) and Lumentum Holdings (NASDAQ:LITE) said they will present a live demonstration of integrated optical networking technologies designed for next-generation artificial ...
