From: Absence of an integrated Stiles–Crawford function for coherent light Journal of Vision. 2011;11(1):19. doi:10.1167/11.1.19 Figure Legend: CCD images (pixel size = 4.65 μm) obtained with 3-mm diameter (a, b) annular and (c, d) half-annular apertures in the (a, c) pupil plane and (b, d) retinal plane. An f 25-mm achromatic lens was used in place of the eye to record the retina-like images. To highlight the appearance of speckles, the rotation of the diffuser was not activated during the 133-ms exposure time.
