1. A method of recording digital hyperspectral amplitude-phase holograms of objects consisting in that the radiation source is separated into two beams, one of which is directed to the object, another device for phase modulation, for example, a movable mirror, reflected from or transmitted through the object beam and a reference beam from the phase modulator is directed to the registration of the plane, such as the CCD, sequentially changing the phase of the reference beam, and for each value of the phase register the light intensity distribution representing a two-dimensional interferogram of the object and reference beams, characterized in that, with to register hyperspectral holograms of the object using a source of polychromatic radiation, and using phase modulation device is scanned path difference δ of the object and reference waves, during which each pixel of the matrix recorded interferogram spectrum of the object field thus obtained interferogram is subjected to the Fourier - transformation of the variable δ and get a set of two-dimensional complex amplitudes of the object field for each spectral chastoty.2. The method of claim. 1, characterized in that, in order to increase the amount of signal to noise ratio and enhance the spectral-spatial resolution of reconstructed images on the recording interferogammy CCD performed for a time equal to several scans zerkala.3 rolling. The method of claim. 1, characterized in that, in order to reduce speckle noise of the recorded holographic image of the object is carried out adding the recovered complex
