In this paper, a 2D angle amplifier based on peristrophic multiplexed volume Bragg gratings is designed and prepared, in which a calculation method is firstly proposed to optimize the number of channels to a minimum. The induction of peristrophic multiplexing reduces the performance difference in one bulk of grating whereas no need to deliberately optimize the fabrication process. It is revealed that a discrete 2D angle deflection range of ±30° is obtained and the relative diffraction efficiency of all the grating channels reaches more than 55% with a Root-Mean-Square deviation of less than 3.4% in the same grating. The deviation of the Bragg incident and exit angle from the expected values is less than 0.07°. It is believed that the proposed 2D angle amplifier has the potential to realize
