<p>The present invention provides an image exposure-recording device for exposure-recording holographic stereogram images or hologram images to a hologram recording medium, the device having an inverse correction system, in which the plane of polarization of reference light R is rotated by a half-wave plate (11), the reference light R is then made incident on a hologram recording medium (3), and the intensity of the reference light R transmitted through a polarizing plate (12), of the reference light R transmitted through a partial area of the hologram recording medium, is detected by a photodetector (13). As the inverse correction system decides the rotation angle of the half-wave plate so that the intensity of the reference light R detected by the photodetector reaches the minimum or maximum, reduction in coherence between object light and reference light due to transmission of the object light and the reference light through the hologram recording medium having double refraction is avoided, and a holographic stereogram based on reproduction of bright holographic stereogram images is produced. <IMAGE></p> |
