The Maxwellian view is a powerful technique to provide visual information to people with refractive error, low vision, and eye diseases. Because images are displayed with rays converging at the center of the pupil of eyes, retinal images are formed independently to the refractive power of the crystalline lens. Conventional Maxwellian-view displays are based on geometrical optics; a lens is used for generating the converging rays. Therefore, some mechanical system is required to move the ray convergence point according to the eye movement. This study proposes the Maxwallian-view display based on computer-generated holography to allow the electronical movement of the ray convergence point. The spatial light modulator (SLM) generates wavefront which produces reconstructed images at any distance and converges at the center of the pupil. Because the inclination and the radius of curvature of the wavefront can be easily controlled using the computer-generated holography technique, the light convergence point can be electronically moved in both the lateral and longitudinal directions. The experimental verification of the proposed technique is shown.
