Abstract
Low-aberration holographic scanners that eliminate the need for lenses or mirrors promise to greatly reduce the cost of laser printers and image scanners. This paper describes how the spot profile of such a scanner can be predicted using the Fresnel-Kirchhoff diffraction integral, and the diffraction efficiency of the scanner can be predicted using Kogelnik’s coupled-wave theory. Experimental results verify the accuracy of these design methods. For a prototype scanner used in a high-resolution He–Ne laser printer, the measured linearity error was under ±100 μm, and the spot size (half-intensity beam width) was under 60 μm for a span (scan width) of 280 mm.
