In LBRCF, standard radiation, reference radiation and the radiation under calibration are coaxial by opticaldeflection, and the use of large-scale sliding tables is therefore avoided.
校准装置内的标准辐射，参考辐射和待测辐射由光学偏转方式进行同轴，使装置避免了大型导轨平台的使用。

The present invention further relates to a method for producing a concentrically fanned, spatially structured bundle of light beams (422), using the opticaldeflection element (150) mentioned above.
此外，本申请还涉及一种使用所述光学偏转元件(150)产生同心发散的空间结构化光束(422)的方法。
