Opticalpattern dynamics is mainly divided into two parts: laser pattern dynamics and pattern dynamics in optical resonator with nonlinear material.
光学斑图动力学主要包括激光器斑图动力学和含有非线性介质的光学谐振腔系统的斑图动力学。

By this filter, the shift, scale and rotation invariant opticalpattern recognition was realized with a high signal noise ratio of correlation output.
用这种滤波器实现了平移、旋转、尺度三重不变光学图像识别,且有较高的信噪比。

The serial encoding method can reduce the diameter of the code disk and simplify the opticalpattern, in favour of miniaturization and high precision of the absolute encoder.
