ABSTRACT:
A method of preparing a color separation holographic master which can be used in the preparation of a colored hologram of an object, by illuminating the object with light having a very narrow wavelength range and capturing the reflectance values on the object using a detector placed as if it were along the axis of the laser to be used for the holographic exposure and storing these reflectance values as a positive image, then carrying out a holographic exposure of the object using a laser there being present in the object beam between the laser and the object as a light modulating means the positive image of the captured reflectance values, and then processing the holographic material to fix the holographic fringes therein.
