How to write the conclusion of the lens imaging recording hologram experiment?

A hologram is equivalent to a complex grating, which will produce dispersion when illuminated by white light, causing images of various wavelengths to overlap with each other, resulting in blurred images. This is the reason why ordinary holograms cannot be reproduced with white light. .

However, the amount of color blur in the reproduced image is related to the dispersion rate of the hologram, the light source linearity and the distance from the image to the hologram
