摘要

The use of a computer-generated hologram(CGH) in interferometric testing provides new methods for highly accurate optical measurement.To fabricate a CGH,polygons are used to approximate the smooth CGH pattern.Because the data size supported by CGH writing machines is limited,the number of polygon vertices must be limited.Therefore,the CGH-encoding method determines the encoding accuracy.To realize a highly accurate optical measurement using CGHs,we propose a CGH-pattern-encoding method based on non-maxima suppression.A self-aligned CGH is designed to verify the accuracy.The experimental result shows that a highly accurate CGH can be fabricated using this method.
