The practicability of reconstructing the kinoform with white-light is discussed.It is drawn that the kinoform can be reconstructed with white-light,if a slit is placed between the kinoform and observer(called as rainbow kinoform).And a method for making rainbow kinoform is proposed.The computer-generated rainbow hologram is calculated.A finite impulse response(FIR) low-pass filter with real coefficients is designed according to the band-width of the object.The FIR band-pass filter with complex coefficient is gained by moving the spectrum of low-pass filter to the position where the spectrum of object is located.And the zero-order and conjugate image is eliminated by filtering the rainbow hologram with designed filter in spatial domain.The kinoform of 3D scenes is made by extracting the object phase distribution of the filtered hologram.In the exprements,the clear reconstructed image of rainbow kinoform is observed under white-light illumination.It is proved that the proposed approach is feasible.
