PURPOSE: A method for generating a Fourier hologram of a 3D object using a multiple orthographic view image and an optical reproducing device thereof are provided to generate and reproduce a hologram based on parallel projection or orthogonal projection, thereby eliminating limits in a reproducing angle and a reproducing distance. CONSTITUTION: An optical reproducing device photographs an object in four directions(S110). The device converts a generated 2D image into a 3D image(S120). The device converts each of the object on the converted 3D image into a point which is projected on an orthogonal projection surface(S130). The device calculates a phase transfer function from each point(S140). The device calculates a Fourier hologram(S150). [Reference numerals] (S110) Generating a plurality of 2D images by photographing an object in all directions; (S120) Converting the 2D images into one 3D image; (S130) Converting and calculating each point O(x,y,z) of the object on the 3D image into point Ps,t(xp,yp) which is projected to a perpendicular projection side; (S140) Calculating phase transfer function Bs,t(xp,yp) from each point O(x,y,z) of the object; (S150) Calculating Fourier hologram H(s,t) by multiplying Px,t(xp,yp) and Bx,t(xp,yp) and respectively double integrating the multiplied values about xp and yp
