WASHINGTON — Researchers have developed a fast and energy-efficient laser-writing method for producing high-density nanostructures in silica glass. These tiny structures can be used for long-term five ...

Rotary encoders convert rotary movement or angular position into analogue or digital signals for use in measurement or control systems. They can be classified in a number of ways, primarily by the ...

Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque and transparent segments passes between an LED and detector to interrupt a light ...

A research team sponsored by the National Science Council (NSC) has successfully developed a "laser encoder system" involving nano-optical technologies, the utilization of which could reduce the ...

Researchers at Shanghai University of Science and Technology have devised a technology that greatly expands the storage capacity of optical discs by recording data three-dimensionally instead of ...

This file type includes high resolution graphics and schematics when applicable. Rotary encoders track motor shaft movement for myriad pieces of industrial equipment and commercial devices. For ...

Building a 3D motor printed motor is one thing, but creating a completely custom servo motor with encoder requires some significant engineering. In the video after the break [365 Robots] takes us ...

Forward-looking: As consumers increasingly turn toward digital distribution and data center operators try various storage methods, optical discs haven't stopped evolving. A recently published paper ...
