Nanopositioning using standing wave piezoelectric motors

In photonics motion control applications, how do you combine speed with nanometric precision and unlimited travel? These seemingly conflicting requirements are uniquely addressed by ultrasonic, standing-wave, direct-drive piezoelectric motors. This technology provides unlimited linear or rotary motion of a ceramic tip that transfers drive to a target, operating in a manner similar to a DC servo motor but with much higher resolution, an order-of-magnitude higher speed and a wider dynamic range.

Position-sensing detectors characteristics

Silicon photodetectors are commonly used for light power measurements in a wide range of applications such as bar-code readers, medical imaging, spectroscopy, and laser printers.  There is another function, however, which utilises the photodetectors as optical position sensors. They are widely referred to as Position Sensing Detectors (PSDs). The applications vary from human eye movement monitoring, 3D modelling of human motion to laser, light source, and mirrors alignment.
