Measurement systems that are able to accommodate evolving application requirements are preferred as growing cost pressures demand long system life and functional flexibility. The most efficient way to ...

Analog and digital optoelectronic sensors combine an LED and an optoelectronic integrated circuit in a compact package to enable optical encoders to provide absolute or incremental position detection ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to ...

New research has shown how the quantum mechanical principle of strong coupling opens unrivalled possibilities for designing optical filters. A team of researchers from the University of Cologne, ...

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 ...

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 ...
