Abstract
We will present an interactive computer-generated hologram technique using spherical angular spectrum. The spherical angular spectrum consists of the frequency spectrum of the object wave in all-around directions. The spherical angular spectrum is computed by a formula of the Fourier coefficients of point light source. Given a spherical angular spectrum, one can generate a planar hologram at a high speed for any given direction. We also present an interactive computer-generated hologram example using a hand-recognition sensor.
