针对传统绝对式光学编码器各编码码道沿径向分布、结构复杂的缺点,提出了一种绝对式光学编码器的串行编码方法。在码盘上仅刻划一圈存储多位二值信息的编码码道,沿码盘圆周方向按一定位置布置的光敏元件并行读取的二进制数具有唯一性,对此二进制数查表译码,就可以实现绝对位置测量。与传统绝对式光学编码器相比,码盘直径小、光学图案简单,有利于绝对式编码器实现小型化和提高精度。 To overcome the shortcomings of the traditional absolute optical encoder in the radial distribution and the complex structure of each code track, a serial encoding method of an absolute optical encoder is proposed. The encoder only scratches the circle to store a plurality of binary information encoded code track along the circumference of the encoder according to a certain position of the photosensitive element parallel read binary number is unique, the binary number look-up table decoding , You can achieve absolute position measurement. Compared with the traditional absolute optical encoder, encoder diameter is small, the optical pattern is simple, is conducive to absolute encoder to achieve miniaturization and improve accuracy.
