Abstract
The optical-logic-array processor (OLAP), using a lensless shadow-casting system, has been applied to execute optical digital image processing for binary objects. The OLAP is an optical digital processor based on techniques of image coding and optical correlation that can optically implement parallel logic gates. To demonstrate further potential of the OLAP, several processing methods for gray-level objects are presented. Experimental results indicate applicability of the OLAP for parallel optical digital image processing for both binary and gray-level objects.Keywords
