摘要： The invention provides a diffusing plate with the angle of diffusion controllable within a desired range by use of a hologram, which is capable of presenting bright displays so that it is applicable to, for instance, a backlighting diffusing plate for liquid crystal display device. A diffusing plate 2 having an angle of diffusion θ is brought into close contact with a hologram photosensitive material 1. Then, parallel light 3 is obliquely at an angle of incidence α on the photosensitive material 1 while parallel light 4 is vertically incident on the diffusing plate 2. Thereupon, parallel light 4 is converted into diffused light 5 having an angle of diffraction θ upon passing through the diffusing plate 2. Diffused light 5 interferes with obliquely incident parallel light 3 from the opposite direction in photosensitive material 1 to produce interference fringes, thereby forming a reflection type hologram. Upon parallel illumination light on the hologram at the same angle of incidence α at which parallel light 3 strikes for recording, diffused light having the same angle of diffraction θ as that of diffused light 5 used for recording is reflected, and diffracted from this reflection type hologram.

摘要： The present disclosure discloses a hologram recording device and a hologram recording method. The hologram recording device comprises an object imaging unit comprising a cavity for accommodating an object whose interior wall is a reflective surface, and a light modulating unit configured to produce incident light and reference light interfering with the incident light and to direct the incident light to the object imaging unit, wherein the cavity is provided with an imaging aperture for imaging of the object and at least one light incidence aperture for allowing the incident light to enter the cavity and irradiate on the object, such that an image of the object is formed at a location corresponding to the imaging aperture outside the cavity, and image light produced upon the imaging of the object interferes with the reference light at the location for recording of an image surface hologram. The object imaging unit in the present disclosure is free from limitations and impact of the lens manufacturing process, and may effectively reduce aberration, and thus improve the imaging quality. Moreover, efficient and convenient one-step hologram recording may be achieved.

摘要： The invention provides a diffusing plate with the angle of diffusion controllable within a desired range by use of a hologram, which is capable of presenting bright displays so that it is applicable to, for instance, a backlighting diffusing plate for liquid crystal display device. A diffusing plate 2 having an angle of diffusion θ is brought into close contact with a hologram photosensitive material 1. Then, parallel light 3 is obliquely at an angle of incidence α on the photosensitive material while parallel light 4 is vertically incident on the diffusing plate 2. Thereupon, parallel light 4 is converted into diffused light 5 having an angle of diffraction θ upon passing through the diffusing plate 2. Diffused light 5 interferes with obliquely incident parallel light 3 from the opposite direction in photosensitive material 1 to produce interference fringes, thereby forming a reflection type hologram. Upon parallel illumination light on the hologram at the same angle of incidence α at which parallel light 3 strikes for recording, diffused light having the same angle of diffraction θ as that of diffused light 5 used for recording is reflected, and diffracted from this reflection type hologram.
