Fiber Optic Rotary Encoder for MRI and NMR Applications
Fri, 08/28/2009 - 12:02pm
The MR318 fiber optic rotary encoder is designed specifically for use as feedback in motion control systems operating in extreme electromagnetic fields. The sensor's passive optical design and non-metallic construction has no effect on MRI (magnetic resonance imaging) or NMR (nuclear magnetic resonance) system operation or measurements. The multiturn encoder system offers 360 ppr resolution and measures both angular position and shaft speed. MRI-related applications include feedback for actuator or motor control, monitoring patient position, or correlating foot pedal position for fMRI diagnostics.
