With a 5-mm vertical slot, 0.5-mm aperture, 0.4-mm resolution and a 10% (typ.) current transfer ratio, the TCST1210 transmissive optical sensor is designed to provide highly accurate sensing 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 ...

A design of microstructured optical fibre (MOF) that features a slot running along its length to expose its core could potentially provide a convenient answer to real-time sensing of chemicals and ...

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 ...

At some time or another, we’ve all had an idea we thought was so clever that we jumped on the Internet to see if somebody else had already come up with it. Most of the time, they have. But on the off ...

Researchers have developed the first fully-integrated, non-dispersive infrared (NDIR) gas sensor enabled by specially engineered synthetic materials known as metamaterials. The sensor has no moving ...
