Abstract
A method of making a synthetic focused image hologram consisting of: PA1 A step to diffusely illuminate plural number of component pictures having different image informations with coherent beam, a step to image by an imaging optical system the images of the plural number of component pictures having different image informations on a hologram recording medium, PA1 A step to irradiate a coherent reference beam on a hologram recording medium, and PA1 A step to have the beam from the component pictures and the reference beam interfere with each other and to record the interference fringes generated by said interference on the recording medium.
