After researching the current applications, problems, and evaluation techniques of planetary microfilming systems, the authors designed and constructed a standard Planetary Microfilming camera Target Array (PMTA) that essentially satisfied three criteria, i.e. 1) inexpensive to produce, 2) simple to use, and 3) satisfies testing criteria for both microfilming equipment manufacture and user. Ten evaluation parameters were incorporated in two targets PMTA-I and PMTA-II. PMTA-I includes tests for 1) resolution, 2) readability of printed matter, 3) reduction ratio, 4) exposure and processing, 5) full field visual distortion, and finally 6) corner visual distortion. PMTA-II was designed to evaluate, 7) quatitative distortion, 8) continous tone, 9) evenness of illumination, and 10) alignment of microfilming system.
