To reconstruct a image on arbitrary tilted plane from a digital hologram, a reconstruction method based on angular spectrum transform and interpolation processing method is proposed. The angular spectrum diffraction theory is applied to analyze the proposed method. Two interpolation algorithms of forward and inverse spectrum rotations are presented. The sampling interval is analyzed based on the condition of information conservation of rotation transform. It′s shown that the interval values depend on the bandwidth of the spectrum on tilted plane and the spatial-band width product of the hologram. The holographic reconstruction is realized on a 71° single axis rotation. The partially defocus blurred aberration resulted from the tilted object plane is removed by this method. Meanwhile the range of sampling interval on tilted plane is presented.
