  • Patent number: 11009373
    Abstract: An optical encoding device includes a code disc, an optical signal generator, (K+1) optical sensors and an encoding circuit. The code disk has K gratings arranged in a row. The total width of the optical sensors is equal to the total width W of the gratings. The optical sensor receives the optical signal through the code disk. Each optical sensor converts the optical signal into a voltage signal and outputs the voltage signal. The encoding circuit receives and normalizes the voltage signals to generate (K+1) voltage values. During a period in which the code disk rotates by a distance of 2W/K, the encoding circuit compares the voltage values with a preset value to generate at least two binary codes. When K is odd, the preset value is 0.5, and when K is even, the preset value is 0.55. The present invention can increase an absolute row resolution of the code disc.
