a, Comparison of holographic rendering techniques using experimentally captured results with different focus states (far: 0 D, middle: 1.5 D, near: 2.5 D) and pupil positions. b, Experimental results with various pupil sizes demonstrate robust image quality in the focused object (left insets), with correctly represented depth of field (right insets) according to the pupil size. RGB channel images were captured separately at the same wavelength and merged to enhance the visual perception of the 3D effect and image quality (pseudo-colour).
