- Abstract
- An apparatus for measuring a spatial resolution of a hologram reconstructed image optically reconstructed on a space is provided. The apparatus for measuring a spatial resolution of a hologram reconstructed image includes: a measuring unit measuring first spatial frequency resolving powers for a horizontal direction of the hologram reconstructed image and second spatial frequency resolving powers for a vertical direction of the hologram reconstructed image at first spatial positions having a predetermined interval in horizontal and vertical directions within a viewing angle range of the hologram reconstructed image; and an evaluating unit evaluating the spatial resolution of the hologram reconstructed image using the first spatial frequency resolving powers and the second spatial frequency resolving powers measured at each of the first spatial positions.
