An experiment was run to determine if differences in drying temperature humidity conditions have any effect on the dimensional characteristics of five quite different aerial films used for various military applications. Acutance measurements were made from microdensitometer traces of each film-temperature and the data was statistically analysed.
Each sample was exposed through a precision stainless steel template to a density of about 1.0. Using an optical comparitor, the difference in size between the film and the template was measured to 10-4 inch. As the image is circular, the size in any direction can be found by mere rotation on the comparitor. The length and width directions were used.
The statistical analysis shows the degree to which each factor affects the results. The dimensional data agrees favorably with published data.
