a Optical setup for recording a hologram. b1 The TwPCPR process, where ① is the in-line recording at distance z 1, ② is the in-line recording at distance z 2, and ③ is the off-axis recording at distance z 2. b2 Bandwidth limitation of holography in normalized coordinates, where Δ is the pixel size of the camera, NA is numerical aperture, and λ is wavelength. b3 Reconstructed Peak Signal-to-Noise Ratio (PSNR) for different holographic imaging methods. c Reconstructions for different holographic imaging methods
