采用循环Ｓ－矩阵设计了一维和二维循环编码构形，使仪器的编码测量过程大为简化。基于π变换和快速阿达玛变换的解码算法，将矩阵乘法简化为矩阵元素间的加、减运算和位置交换，降低了仪器对微机系统的要求。
The cyclic S-matrix is used to design the one-dimensional and two-dimensional cyclic coding configuration, which simplifies the coding and measuring process of the instrument. The decoding algorithm based on π transform and fast Hadamard transform simplifies the matrix multiplication to the addition, subtraction and location exchange among the matrix elements, which reduces the requirements of the instrument to the microcomputer system.
