Canon Ultra Small High Precision Encoder
|
From Canon USA Encoders/Optoelectronic Components Group
Encoders are sensors that convert positional changes into electrical signals using high-precision scales (graduations). Drawing on its store of original technologies, Canon developed an ultra-compact encoder with a 4 x 5 mm detection head capable of high-resolution (0.1 µm) position detection. Achieving significantly reduced power consumption thanks to its MRA (Micro Roofmirror Array) scale and high-sensitivity, low-noise SR sensor, Canon's ultra-compact encoder is used in the company's digital video camcorders, interchangeable lenses (EF lenses) for SLR cameras, and broadcast television lenses. Other types of encoders include ultrahigh resolution laser rotary encoders that rely on optical diffraction and interference. Products & Services
Incremental rotary encoders are multi-turn sensors that use optical, mechanical, or magnetic index-counting for angular measurement. They contain no absolute reference, but instead count relative to the turn-on position.
