METHOD FOR GENERATING FOURIER HOLOGRAM OF 3D OBJECT USING MULTIPLE ORTHOGRAPHIC VIEW IMAGE AND OPTICAL APPARATUS FOR LOADING THE FOURIER HOLOGRAM

摘要

to record the object in all directions, and generating a plurality of 2D images, the 2D image generated and converting into a 3D image, each point of the object on the converted 3D image O (x, y, z) that is projected onto a projection plane orthogonal to P _{s , t} (x _p , y _p ) as calculated by the steps of: converting, for each point of the object O (x, y, z) from the B phase, wherein _{s , t} (x _p , y _p ) and calculating, the calculated P _{s , t} (x _p , y _p ) and the calculated B _{s , t} (x _p , y _p ), multiply the value obtained by multiplying the x _p and y _{p Each double integration with respect to} constitutes a step of calculating a Fourier hologram H (s, t). According to the above, parallel projection (parallel projection) by creating a hologram, and on the basis of the reproduction naejineun orthogonal projection (orthographic projection), eliminating the restriction of the reproduction distance or angle. Thus, there is an effect that can be reversed or at random to change the reproduction distance naejineun the phase rotation. Further, the computer generated hologram (computer generated hologram, CGH) by, depending on how the hologram generation, the problem of the minute vibration and the optical system to be exposed for an extended time in the recording medium of the optical system is removed. On the other hand, 2D image by using a 3D image, not to create a hologram, there is an effect that can be generated by a hologram having a three-dimensional face of the object, as well as with respect to the entire surface of the object. ;
