Effect of design parameters on image quality, indicated by the peak signal‐to‐noise ratio (PSNR). a) Increased sound velocity range (Δc _m) and reduced minimum sound velocity (c _min) improve the reconstructed image quality. b) Image quality degrades as the number of images programmed in a hologram increases. PSNR is calculated based on the normalized target image magnitude and binary input image windowed to 108 × 68 pixels. Figure S4 (Supporting Information) shows the resulting images for Figure 5b.
