Paper Abstract

The authors describe visual resolution characteristics of an array comprising many afocal optical units. It is shown by wave optics that light beams exiting the array will converge, forming a three- dimensional optical image. It is also clarified that the converging point and resolution are dependent on the angular magnification of the afocal unit. When the magnification is 1.0, the optical wave focuses on the converging point, and the resolution is dependent only on the diffraction of the afocal unit. If the magnification is not 1.0, the optical wave does not focus on the converging point, affecting the resolution as a result. Based on this, we have obtained viewing distances and object distances at which the effects on the resolution by diffraction or defocusing are not perceptible when an optical image formed by the array is viewed by an observer.
