辐射是聚变等离子体能量损失的主要途径之一。由于辐射分布具有复杂的三维结构的螺旋装置，如一个大的螺旋装置（LHD），三维辐射测量，需要了解聚变等离子体的功率平衡。红外成像视频测辐射热计（IRVB）安装在LHD检查作为一个系统的3-D成像使用的投影矩阵，得到的假设下，等离子体周期性的环形方向，并使用数值计算得到的幻影与EMC 3-EIRENE代码作为杂质分布。重建的轮廓表明，目前的IRVB系统的能力，成像的三维辐射分布在LHD。
Radiation is one of the major paths of power loss from fusion plasmas. Since the radiation distribution has a complex 3-D structure in helical devices, such as a large helical device (LHD), 3-D radiation measurements, are required for understanding the power balance of fusion plasmas. IR imaging video bolometers (IRVBs) installed in the LHD were examined as one system of 3-D imaging using a projection matrix that is obtained under the assumption of plasma periodicity in the toroidal direction, and using the phantoms obtained numerically with the EMC3-EIRENE code as the impurity distribution. The reconstructed profiles indicate the capability of the current system of IRVBs for imaging the 3-D radiation distribution in LHD.
