The simplest example is an optical rotary encoder. In a contained system with a bearing, you have a glass disk aligned to the bearing center, and a stator portion that holds the electronics and scans ...

For example, the feedback from an optical rotary encoder can be used to accurately determine the current position of each individual pivot joint of a robotic arm. Using this data, a controller can ...

At our company, encoders with optical, magnetic, and capacitive sensing technologies are used for safety applications. This requires that all mentioned sensor technologies be able to process analog, ...

The proposed encoder in two dimensional photonic crystals is analyzed in terms of flow of light inside waveguides. Waveguides have been created by removing silicon rods in the structure and defects ...

More than that, the optical encoder could also detect whether or not the filament was actually moving through the extruder.

This paper discusses the design, realization and demonstration of high resolution absolute optical encoder based on a piecewise linear estimate of the sinusoidal signals. Opto-mechanical elements are ...
