Abstract
An improved register of spatially placed object wave information wherein the register is of the type comprising a dimensionally stable medium having a surface on which a raised pattern is placed, the raised pattern comprising a spatial carrier wavelength which is spatially modulated according to the object wave information with the shortest space wavelength contained in the object wave information being longer than the space carrier wavelength whereby the relief pattern it is capable of diffracting certain wave energy that illuminates the relief pattern on the medium in order to demodulate and recover the wave information of the object; the improvement in which is that only the amplitude of the wavelength of the spatially modulated space carrier of the relief pattern varies according to the information of the wave of the object so that the frequency and phase of the wavelength of the spatially modulated spatial carrier of the relief pattern are independent of the waveform information of the object and said quoted energy may be an extended source.
