1. An apparatus which analyses a depth of a holographic image, the apparatus comprising:
an acquisition device configured to acquire a hologram;
a restoration device configured to restore a three-dimensional holographic image by irradiating the hologram with a light source;
an image sensor configured to sense a depth information image of the restored holographic image; and
a processor configured to execute instructions; and
a memory storing the instructions, wherein execution of the instructions configures the processor to:
analyze a depth quality of the holographic image, based on the sensed depth information image,
wherein the image sensor senses the depth information image through a lensless type of photosensor,
wherein the image sensor comprises:
a plurality of transparent plane photosensors configured to measure the holographic image restored by the restoration device; and
at least one electric rail configured to move the plurality of transparent plane photosensors in a depth direction of the holographic image,
wherein the plurality of transparent plane photo sensors comprises:
a first transparent plane photosensor configured to move in a depth direction of a first region of a holographic space in which the restored holographic image is displayed; and
a second transparent plane photosensor configured to move in a depth direction of a second region of the holographic space.
