Image quality assessment procedure for holographic displays based on exact numerical reconstruction of computer-generated holograms

We proposed a technique for the computer-based reconstruction of computer-generated holograms and evaluation of the reconstructed 3D image quality. The proposed method mimics how the eye's lens works, thus allowing for viewing position and eye focus adjustments. The angular resolution of the eye was used to output reconstructed images with the requisite resolution, and a reference object was used to normalize the images. Such data processing enables the numerical analysis of image quality. By comparing the reconstructed images with the original image with incoherent illumination, the image quality was quantitatively evaluated. (c) 2023 Optica Publishing Group

Automated summary

This study proposes a technique for reconstructing computer-generated holograms and evaluating the quality of the reconstructed 3D images. The method mimics the lens of the eye, allowing adjustments of viewing position and eye focus. The angular resolution of the eye is used to output reconstructed images with the necessary resolution, and a reference object is used for image normalization. This enables numerical analysis of image quality. By comparing the reconstructed images with the original image under incoherent illumination, the image quality is quantitatively evaluated.
