Abstract
Current holographic displays suffer from low étendue, limiting either field-of-view (FOV) or display size due to the spatial resolution constraints of spatial light modulators (SLMs). This paper introduces neural étendue expanders, learned optical elements that enhance diffraction angles for ultra-wide FOV while preserving image fidelity. Experiments demonstrate a 64x étendue expansion with high-fidelity reconstruction (PSNR > 29 dB) for full-color natural images, achieving an order-of-magnitude FOV increase.
