| Abstract: | The feasibility of the determination of the image sharpness and MTF by a scanner was discussed,and some sharpnesses of T-grain,cubic and potato-shaped AgBrI photographic emulsions were determined by the scanner and the PDS microdensitometer,respectively,and MTFs of the commercial black white film developed by different developers were obtained with the same procedures.The results show that a less expensive scanner could be substitute for the noble microdensitometer. |
