Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

A digital camera has an array of sensors that captures light reflected or transmitted onto it. This build is something closer to a reverse camera – a single sensor that makes images on a matrix of ...

(Nanowerk News) A research team led by Prof. CAO Hongtao at the Ningbo Institute of Materials Technology and Engineering of the Chinese Academy of Sciences, in cooperation with Prof. ZHANG Haizhong's ...

Converting light into electrical signals is essential for a number of future applications including imaging, optical communication and biomedical sensing. Researchers have now developed a new ...

Historically, applications that must sense a light stimulus to execute a function have relied on a photodiode or a phototransistor. Neither of these technologies, however, can support the emerging ...

ROHM's RPR-0730 Analog Compact Optical Sensor Capable of high-precision detection of fast-moving objects. Relationship Between Line Width and Speed RPR-0730 achieves high-speed and high-precision ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Intelligent light grids take many forms and cover applications from simple to complex. Sizes range from a few inches to several feet, and resolutions from 2 to 100 mm. Automation light grids take many ...

The devices, which operate on a heterojunction-gated (HG) structure, demonstrate high responsivity and detectivity while maintaining a simplified fabrication process. This approach avoids the ...
