Fourier hologram generation of 3D objects using multiple orthographic view images captured by lens array

Abstract

We propose a new synthesis method for the hologram of 3D objects using multiple orthographic view images captured by lens array. The 3D objects are captured through a lens array under normal incoherent illumination, and their multiple orthographic view images are generated from the captured image. Each orthographic view image is numerically overridden by the plane wave propagating at the direction of the corresponding projection angle and integrated into a single complex value, which constitutes one pixel in the synthesized hologram. By repeating this process for all orthographic view images, we can generate the Fourier hologram of the 3D objects. Since the proposed method generates the hologram not from the interference with the reference beam, but from the multiple view images, coherent system is not required. The manipulation of the 3D information of the objects is also easily achieved in the proposed method. By manipulating coordinate information of each orthographic view image according corresponding view angle, the depth order of the reconstructed 3D object can be controlled.
