Abstract
A system has been developed to process sequences of field-ion micrographs, and imaging atom probe micrographs and elemental maps. The system consists of a commercial video digitizer capable of digitizing standard RS-170, or RS-330 video input and a frame memory that can store the digitized image in memory. The video digitizer is an additional single-board subsystem incorporated in the ORNL atom probe IBM-PC AT microcomputer. The resolution of the system is 512 horizontal by 480 vertical with 12 bits of memory associated with each pixel. The system can digitize data either from real time images of from recorded images on video tape or from prints or negatives.
