Transparency function presentation of computer generated Fourier holograms for complex data page restoration

“…22) The reduction of phase modulation depth can be possible resolution to this problem. 23) The affect of such a conversion to amplitude and phase of the restored object was not discussed. In the present article this problem is investigated numerically by means of computational restoration and analysis of amplitude and phase of data pages images by CGFH models realized using basic types of light modulation: amplitude-only, phase-only or mixed amplitude and phase.…”
