可以考虑利用FPGA来构成系统检测获取偏振图像的Stokes矢量，而

由Stokes矢量来计算偏振角利用FPGA实现就比较复杂，往往又利用软件来实现，这

与最初利用FPGA硬件实现偏振图像的Stokes矢量计算达到实时性要求的初衷不符，

因此有必要设计出一种利用FPGA来硬件实现actan函数的计算的方法。

-Can be considered to constitute a system test using FPGA to obtain polarization images of the Stokes vector, calculated by the Stokes vector polarization angle using FPGA implementation is more complex, they often use software to achieve this with the first use of FPGA hardware implementation of the Stokes vector calculation of the polarization image to match real-time requirements in mind, it is necessary to design a hardware implementation using FPGA actan function calculation.
