一种提高光码盘检测分辨率的电路逄海萍（山东建材学院，济南，２５００２２）在高精度伺服系统中一般采用光码盘检测速度和位置信号。光码盘的周脉冲数决定了它的检测分辨率。对于一选定的光码盘，为了进一步提高检测分辨率，可外加一变换电路，将光码盘的输出脉冲的频率... A Circuit for Increasing the Resolution of Optical Code Detector 逄 Haiping (Shandong Institute of Building Materials, Jinan 250022, China) Optical encoder is used to detect speed and position signals in high precision servo system. The number of pulses in the optical coder determines its detection resolution. For a selected optical code disk, in order to further improve the detection resolution, an additional conversion circuit can be added, and the optical pulse output pulse frequency ...
