Validation of objective evaluation in a computer-generated hologram

Abstract

Various computer-generated holograms (CGH) have been studied to reconstruct complex and resolution images. We have evaluated objectively with structural similarity (SSIM) showing the reproducibility of CGH and diffraction efficiency showing brightness, and studied the difference in image quality by calculation method. However, we have not yet compared objective evaluation and subjective evaluation. Therefore, in this study, we compare the objective image quality evaluation of Fourier transform hologram, subjective image quality evaluation, and subjective evaluation of optically reconstructed CGH and validate the objective image quality evaluation method.
