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 ...

Motion blur can be caused by interpolating frames, algorithms can help with this problem. The BBC has always pushed boundaries to achieve better video quality for both streaming and broadcasting - one ...

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 ...

The BBC has always pushed boundaries to achieve better video quality for both streaming and broadcasting - one example is the BBC’s contribution to the Ultra High Definition (UHD) standard. Many TVs ...

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 ...

HEIDENHAIN’s family of KGM grid encoders have once again been improved to better meet the needs of CNC-controlled machine users who require accuracy testing. Now the KGM 281 grid encoder is available ...

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 ...
