A new design of a multi-path Thomson scattering system with signal delay function based on a polarization control technique is proposed on Heliotron J to deal with the overlapping phenomenon of scattered light signals. By operating double Pockels cells to control the injection timing of the laser beam into plasma, the adjacent scattering signals corresponding to opposite incident laser beams are expected to be separated to some extent for better analyzing the anisotropic temperature. Two image relay systems are also designed and integrated into the system to suppress the reduction of the laser beam power during multi-path propagation. Estimations are made on residual power of laser and separation degree of adjacent scattered light signals to reveal the feasibility of this new design. This design is instructive for fusion devices that desire anisotropic measurement but also face limitations of less setting optical path.
