Abstract
Modulation transfer functions (MTFs) of the screen-film systems were compared among the results obtained at ten cooperating facilities. Three kinds of green screen-film systems were purchased at the Kumamoto University. Each facility prepared sensitometric strips and slit images. and analyzed its own samples. Results indicated that the MTF data measured at ten facilities showed significantly large fructuation.
