Download or read book Luminance Thresholds for the Resolution of Visual Detail During Dark Adaptation Following Different Durations of Light Adaptation written by Aaron L. Diamond and published by . This book was released on 1952 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Luminance thresholds for the visual resolution of various widths of alternating light and dark lines determined at various times during recovery from different durations of light adaptation. Increasing duration of preadaptation from one second to five minutes raises the initial dark adaptation thresholds and decreases the speed of the recovery process. The level of visual acuity determines the range of luminance covered by the dark adaptation curves.
