It takes considerable time and effort to manufacture “perfect” surfaces. The mirrors on NASA’s James Webb Space Telescope, with a surface area of about 25 m 2 and finished to accuracies of 25 nm, took ...

Direct drives place rigorous demands on position-signal quality. Optimum measuring signals increase the quality of the machined workpiece surface, reduce vibration in the machine frame, stop excessive ...

Avago Technologies today announced the market’s smallest three-channel reflective encoder. The new AEDR-850x encoders feature built-in interpolation for high-resolution measurement that is ideal for a ...

A high-accuracy 20-bit resolution quasi-absolute encoder with DSP-based signal processing is housed in a dc stepper motor assembly, as shown in Fig. 1. Able to operate in a temperature range between ...

Renishaw, is adding to its extensive optical encoder range with the launch of the Vionic series, a new set of ultra-high accuracy, super-compact all-in-one digital incremental encoders. Designed for ...

From pan-tilt-zoom cameras to the most highly sophisticated mini robots on the market, a wide array of today’s technologies incorporate some form of motion control system. At the heart of these ...
