According to the spatial frequencies distribution of different holographic recording systems, we proposed the spatial frequency density to analyze the framing capability of high-speed digital holography. In our results, by increasing the spatial frequency density, the framing capability of high-speed digital holography can be improved. The spatial frequency density can be increased through recording with long-wavelength light source, far recording distance under resolution requirement, and using CCD with small pixel size when recording the same object with plane reference wave. In the spherical reference wave case, the density can also be increased by adjusting the location of object and point source reference. Furthermore, simulations were calculated to analyze the framing capability of high-speed digital holography in different systems. The simulated results agreed well with the theory.
