Patent ID: 7733297

Claim:
A three-dimensional image display apparatus which displays a three-dimensional image using an interference fringe calculated by an interference fringe computing apparatus which calculates the interference fringe generated by an object beam and a reference beam, the apparatus comprising: a light modulation device having an electro-optic effect in which a refractive index changes according to electric field intensity; a plurality of control points provided on a surface of the light modulation device; a storage section configured to store a table in which each of a plurality of voltage values to be applied to each of the plurality of control points is associated with an image pattern of the interference fringe to which crosstalk is reflected; a determination section configured to select the image pattern of the interference fringe which is the most similar to a calculated interference fringe, and determine the plurality of voltage values in association with a selected image pattern of the interference fringe; and an electric field control section configured to apply a voltage corresponding to each of the plurality of voltage values determined by the determination section to each of the plurality of control points, and to form electric field displacement surfaces having the image pattern of the interference fringe which is the most similar to the calculated interference fringe, in the light modulation device.
