Abstract :
Results of the investigation of the viability of using a coherent optical processor to improve image quality prior to digitization and analysis are presented. Optical processing of small (20 mm*20 mm) and large (100 mm*100 mm) radiological images to improve contrast and enhance edges is demonstrated. A brief summary of the principle of operation of the coherent optical processor is given. Results obtained with the apparatus described here are presented and discussed.<>
