20140326863 | OPTICAL ENCODER - The optical encoder according to the present disclosure includes a light receiving part formed with a plurality of first patterns, and a scale formed with second patterns and moving relative to the light receiving part, wherein at least one of the first pattern and the second pattern is formed in a bent band shape to obtain an electric signal of reliable sinusoidal wave shape. | 11-06-2014 |
20140326862 | OPTICAL ENCODER - The optical encoder according to the present disclosure includes a light receiving part formed with a plurality of first patterns, and a scale formed with second patterns and moving relative to the light receiving part, where at least one of the first and second patterns is aligned at a same interval to remove harmonic waves. | 11-06-2014 |
20140299755 | OPTICAL ENCODER - Provided is an optical encoder, including: a light receiving unit; and a scale moving relatively to the light receiving unit and including a first track and a second track each having patterns intended for projecting light onto the light receiving unit, wherein the number of patterns of the first track is Ns*Nd+i (where, Ns and i are an integer of 1 or greater, and Nd is an integer of 2 or greater), and the number of patterns of the second track is (Ns−1)*Nd+i, so an absolute angle of the scale can be calculated in real time and in high resolution. | 10-09-2014 |
