Joint-TEXT上的远红外偏振仪-干涉仪系统（POLARIS）最近进行了升级。 POLARIS的混频器阵列采用了一种新的支撑结构，可以精确调整混频器的位置。通过优化分束栅两侧激光束的利用效率，系统在低场侧增加了五个检测弦。空间分辨率可从3cm提高到1.5cm。系统升级后，对等离子体电子密度和电流密度进行了更好的测量。初步实验结果将与升级细节一起介绍。
The far infrared polarimeter–interferometer system (POLARIS) on the Joint-TEXT has been upgraded recently. A new support structure has been applied to the mixer array of the POLARIS for adjusting the position of the mixers precisely. Five detection chords have been added to the system on the low field side by optimizing the utilization efficiency of the laser beams on both sides of the beam splitting grid. The spatial resolution can be improved from 3 to 1.5cm. A better measurement on plasma electron density and current density has been obtained after the system is upgraded. The initial experimental result will be introduced along with the upgrade details.
