| Abstract: | In this paper, the limitation for choosing the scale factor of an optical system in an optical wavelet transformation is analysed; a minimal scale factor of an optical system is determined in corresponding to an optical wavelet transformation; and the minima of scale factor in a 4F optical processor are calculated for the transformation with a few of specified wavelet functions, some significant data are provided for the application for wavelet transformation in real optical information processor. |
