In order to make the sampled signal uniform,a frequency-change sampling algorithm is proposed based on the coarse code of the encoder. And the compensating parameters could be updated adaptively by switching the modes to reduce the error ratio of the encoder caused by the severe environment.
通过比较分析,采用相关函数分析法测量各精码周期莫尔条纹的正交偏差,并基于系统自身的粗码信息,构造一种智能采样算法,保证莫尔条纹采样均匀性;在工作中对所有精码周期的莫尔条纹实行数字式实时补偿,并可以通过模式间的切换自适应地更新正交偏差补偿参数,持续地保证补偿的精确性,降低编码器在各种恶劣环境下的误码率。
