A performance specification is provided in this report for an Optical Automatic Car Identification (OACI) scanner system which features 6% improved readability over existing industry scanner systems. It also includes the analysis and rationale which support this specification. This improved system is a result of design and test of selected modifications to existing equipment. It is projected that a cost reduction of fifty percent and a reliability improvement by a factor of three, along with a savings of seventeen hundred dollars per year due to maintainability considerations, could be realized using the new system. Sections of this report contain descriptions of test data showing the improvement in readability for degraded labels and difficult ambient conditions. Also included in this specification are guidelines for a compact, self calibrating scanner requiring no air conditioning. At the conclusion of the hardware and testing phase of the program, the modified scanner configuration was tested and demonstrated in the areas of optics, electronics, data processing, and packaging. Test results are included in this report.
