Fiber-optic sensors work well in tight spots and in applications with a high degree of electrical noise, but care must be taken when specifying these critical components. Sensing part presence in ...

The basics of fiber optic cables and bundles and how they can be used to collect and direct light are discussed in ‘An Introduction to a Spectrometer: Fiber Optic Bundles’. This article will discuss ...

It’s always interesting to see how scientists and engineers have exploited—in the positive sense of the word—somewhat obscure, fundamental physics principles to create innovative sensors. For example, ...

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 ...
