DIGITAL OPTO-ELECTRIC PULSE APPLICATION METHOD FOR CORRECTING BIT ERROR OF VERNIER-TYPE OPTICAL ENCODER |
摘要 |
<p>This disclosure relates to a method for detecting an absolute rotation angle of an optical rotary encoder, and more particularly, to an optical encoder having a signal track for generating a digital pulse which may correct an error when a high-level bit is generated in a Vernier type. The optical encoder according to an embodiment of the present disclosure includes a master track for generating a sinusoidal signal with the fastest cycle, a Vernier track for generating a sinusoidal signal with a cycle smaller than that of the master track by a predetermined value, and a digital track for generating a digital pulse signal with a cycle proportional to the cycle of the sinusoidal signal of the master track.</p> |
