This application note presents the basics of optical spectroscopy. It describes the prism and light separation, the prism-based spectroscope, the reflection grating-based spectroscope and the use of ...

This Design Idea utilizes an optical computer mouse's sensor for measuring rotation of a disk which can be mechanically connected to any sort of rotating apparatus. One feature is to allow adjustment ...

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 ...

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 ...

Today, machine learning permeates our everyday life, with millions of users every day unlocking their phones through facial recognition or passing through AI-enabled automated security checks at ...

Optical or magnetic linear encoders are traditionally used to provide position feedback in applications with frequent product changes or and sophisticated machining. Linear encoders improve the ...

There is a point where taking technology for granted hides some of the incredible capabilities of seemingly simple devices. Optical mice are a great example of this principle, using what are more or ...

Here’s a guide to evaluating and using the latest generation of 3D magnetic sensors, which offer a higher-accuracy alternative to existing 1D Hall-effect sensors. Linear magnetic sensing is becoming ...
