We see from your search that you're looking for information on the term "Rotary Encoder",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release Fibre optic system receives US patent from
Micronor, which we summarised at the time by saying "The wavelength division multiplexing approach used in Micronor's ZapFREE produces a totally passive encoder using no electronics within the sensor".
A couple of weeks before,
we featured the news release Motor feedback system minimises components from
Sick Stegmann: "The user-programmable DiCoder CKS36 provides resolution up to 2,048 pulses per revolution and commutation signals of up to 32 pole pairs".
In June 2007, we covered the news from LG Motion
concerning its Miniscale optical encoder system
- take a look at Optical encoder incorporated into guides
which says: "The Miniscale optical encoder integrated into Schneeberger's miniature recirculating linear motion guides has a resolution of 1um with a repeatability of +/-2um".
Take a look also at the news release from Avago Technologies, Magnetic encoders tolerate harsh environments,
as well as Gauge gets the measure of large-diameter bodies from Bowers Metrology UK,
and Absolute rotary encoder has easy serial interface from AMCI.
