Optical encoders, ngu ai gaw, jak geometry shara htawt sit ai pulsed (sh) digital sensor ntsa na pru wa ai shaft hpe galai shai na matu galai shai ai ladat langai mi rai nga ai, sensor gaw grau law ai langai mi rai nga ai.
General Optical Encoder gaw madung hku nna servo system a grating disc hte electro-optical hpe mu lu ai jak ni lawm ai, hpa majaw nga yang, optical encoder hte motor shaft, motor shingnip shingna, grating hte mawdaw a shingjawng ai alawan ai lam, nhtoi shapraw ai diode ni hte kaga electronic arung arai ni a majaw, n-gun n-gun law law hpe shadawn lu na matu ya aten na motor a lawan ai hpe madun dan lu ai.
Dai hta n-ga, tara agyi wa shingjawng ai lam a matu, code disc mung, nhtoi code pru ai channel langai a phase shai hkat ai lam hpe jaw ya lu ai, dai hte maren, double channel nhtoi code of state galai shai ai lam ni gaw steering a motor hpe dawdan ya lu ai; n-gun madun ai lam a npawt tara hte maren, coding galaw ai jak hpe optical amyu, hte magnetic amyu, hte induction amyu hte capacitor amyu ngu nna garan nna; shi a scale ladat hte signal pru ai hkrang hte maren, can hpe incremental amyu, hte absolute amyu hte mixed amyu 3 ngu nna garan ai.
