Abstract

System mean normalized line spread functions with 90% confidence limits were determined for four emulsions. These emulsions or film materials were Kodak Panatomic-X, H & W Control type #77 , 3M #7842 dry silver , and Xidex DMCF diazo. The method of edge gradient analysis was employed with replication of n = 3. Microdensitometer degradation was not eliminated from these system mean normalized line spread functions. Microdensitometer mean MTFs with 90% confidence limits were determined for different types and/or modes of instrument operation with replication of n = 2. Due to a lack of precision in the determination of the system mean normalized line spread functions, definite differences could not be firmly established between these functions with regard to their comparison. This lack of precision was primarily attributable to the type of microdensitometer operation which was utilized. This type of operation proved to be of insufficient precision. Adjacency effects and Newton's rings which were present in the edge images also contributed to the variability.
