摘要： PROBLEM TO BE SOLVED: To provide a projection type video display device which effectively and sufficiently suppresses generation of a speckle, using a coherent light source.SOLUTION: A laser beam L50 generated by a laser source 50 is reflected by a light beam scanner 60, allowing a hologram recording medium 45 to be exposed to the beam. An image 35 of a scattering plate is recorded as a hologram in the hologram recording medium 45, using a reference beam converging to a scanning reference point B. The light beam scanner 60 bends the laser beam L50 at the scanning reference point B, so that the hologram recording medium 45 is exposed to the beam. On this occasion, the bending mode of the laser beam is varied with time, such that the position of the hologram recording medium 45 exposed to a bent laser beam L60 is varied with time during scanning. Irrespective of the exposure position of the beam, a diffraction beam L45 from the hologram recording medium 45 creates a reproduced image 35 of the scattering plate on a spatial light modulator 200. The modulated image on the spatial light modulator 200 is projected on a screen 400 with a projection optical system 300.

摘要： PROBLEM TO BE SOLVED: To provide a method for duplicating a hologram medium to be good quality, which is suitable for a mass production.SOLUTION: A photosensitive recording medium 20 is located under an original plate 10, and reproducing illumination light L having a wavelength λ is radiated from above. Interference fringes which are obtained below the original plate 10 and which are generated by zero order light L0 and one order diffraction light L1 are recorded on the recording medium 20. Concerning a photosensitive material forming the medium 20, when a ratio between "the critical exposure amount Ecri obtained just before the change of refractive index" and "the saturation exposure amount Esat obtained when the change of refractive index is saturated" is R(E)=Ecri/Esat, a thickness of the original plate 10 is made large enough so that an intensity ratio of "minus one order diffraction light L-1" and "two order diffraction light L2" to "one order diffraction light L1" entering from the lower surface of the original plate 10 attenuates to R(E) or under. After the exposure amount of the diffraction light L1 reaches the saturation exposure amount Esat and before the exposure amounts of the diffraction lights L-1 and L2 exceed the critical exposure amount Ecri, the radiation of the reproducing illumination light L is finished.

摘要： PROBLEM TO BE SOLVED: To suppress the generation of a speckle at the time of reproducing a hologram image by using a coherent light beam.SOLUTION: A stereoscopic image display device includes a laser source 50, a light beam scanner 60, and an illumination hologram recording medium 45. A beam L50 from the laser source 50 is reflected by the light beam scanner 60 to irradiate the illumination hologram recording medium 45 with the beam 50. An image 35 of a scattering plate using a reference light beam to be converged on a scan base point B is recorded as a hologram in the medium 45. The light beam scanner 60 irradiates the medium 45 with the beam L50 refracted at the scan base point B. At this moment, a refraction state of the light beam is changed in time so as to scan the light beam 60 on the medium 45. Regardless of the radiation position of the light beam, a diffraction light beam L45 from the medium 45 reproduces a reproduced image 35 of the same scattering plate at the same position. When a spatial light modulator 80 is disposed at the position of the reproduced image 35 and a hologram interference fringe based on predetermined image data is formed, a reproduced image FF having a suppressed speckle is observed from an eye point E.
