Computer-generated holograms (CGH) can generate the ideal wavefront required for any aspheric surface to be measured for phase compensation. It is usually used to create a cylindrical wavefront to replace the null compensator in cylindrical interferometry. Compared with the null compensator, the error components introduced by CGH are more complex, including substrate error, etching error, coding error, etc. The error calibration of the wavefront generated by the CGH can effectively improve the accuracy of the measurement results. Since CGH will generate multi-order diffraction wavefronts, there is frequency aliasing in multiple groups of fringes, so its wavefront cannot be measured directly. A physical model of the multi-order diffracted wavefronts emitted by CGH is established, and the interference of multiple sets of wavefronts is simulated numerically. To solve the frequency aliasing problem, a tilted carrier beam is introduced by using transmission holography to separate the frequency of the target wavefront from those of the other orders. Thus, the frequency of the target order is extracted, and the cylindrical wavefront is recovered according to its frequency. In this paper, the distribution of experimental fringes is consistent with the simulated fringes, which verifies the accuracy of the physical model. The simulation results show that the proposed method can theoretically separate and recover the cylindrical wavefront well, proving the method's theoretical feasibility.
