  • In order to realize the high precise wavefront test of large-aperture collimator and evaluate its wavefront quality, the method of differential pentaprism scanning wavefront detection is proposed in this paper. This method is the optimization of pentaprism scanning detection. Firstly, the information of wavefront curvature is obtained by measuring wavefront slope change to reconstruct the wavefront. The title and defocus error instructed by inaccurate calibration of center of mass are eliminated. Secondly, the differential pentaprism scanning wavefront detection system is established to verify the feasibility of this method. Lastly, the error analysis is given. The error analysis shows that the testing precise of this method is 10.54 nm. The experimental results show that the repeatability precisions of wave peak and valley value(PV) and root mean square(RMS) are increased by 74.41% and 125.81% compared with pentaprism scanning method. This method basically meets the requirements of high accuracy and good stability for collimator wavefront detection, which can be used to evaluate the quality of collimator wavefront.
