US 2022/0043393 A1 · ON-AXIS AND OFF-AXIS DIGITAL HOLOGRAM GENERATING DEVICE AND METHOD

Abstract

Provided are on-axis and off-axis digital hologram generating device and method. The on-axis and off-axis digital hologram generating device includes a controller and an input window configured to receive user input of hologram property information. The controller is configured to access a phase file of an object stored in a storage device, convert the phase file of the object into object phase information in a useable form, generate digital object light information based on a light property of object light input by a user and the converted object phase information, and generate a digital hologram based on (i) the received hologram property information, (ii) the generated digital object light information, and (iii) digital reference light information inputted by a user.
