Fourier analysis and a computer were used to generate the Fourier series and coefficients for the transmission distribution of a square wave target and the effective exposure produced on Kodak Plus-X film. This was performed in an effort to find a workable alternative to the proposed American National Standards Institute (ANSI) method for the determination of the photographic modulation transfer function. The results showed that the square wave method generated a curve with the same general trend as the conventional ANSI method. The Fourier analyzed square wave method had a greater degree of variability than did the standard method. The square wave targets used for the determination were manufactured at the Rochester Institute of Technology.
