    摘要: There are provided a hologram laminate and a hologram label which do not involve any problem in the production process per se of forging preventive labels using a volume hologram, can provide a reliable process of the attainment of forgery preventive effect, and can make difficult to notice the signs of the forgery preventive processing. In applying a protective film 108 onto a hologram 107 through a second pressure-sensitive adhesive 109, the adhesive strength is partially varied. By virtue of this construction, upon separation of the protective film 108, the second pressure-sensitive adhesive 109 is partially left on the hologram 107, so that the fact of the separation can be found out. Likewise, the adhesive strength of a first pressure-sensitive adhesive 106 can be partially changed. Further, the adhesive strength of the first pressure-sensitive adhesive 106 is larger than 1% tensile strength of the hologram 107. This can realize a property such that, as soon as the separation of the hologram 107 is attempted, the hologram 107 is elongated and undergoes a color change.

    摘要: A method for producing a hologram recording an interference fringe formed by an object light and a reference light on a photosensitive dry plate, and the object light either having diffusing and scattering characteristics or being passed through an optical diffusion body, mainly includes the following steps: In a first step, a ratio &eegr;RO/&eegr;OO of a first diffraction efficiency &eegr;OO and a second diffraction efficiency &eegr;RO, is calculated. The diffraction efficiency &eegr;OO is dependent on two object light beams. The efficiency &eegr;RO is dependent on the object light and the reference light. In a second step, the intensity EO of the object light and the intensity ER of the reference light is adjusted in such a way that the ratio &eegr;RO/&eegr;OO is set to at least 10 and the efficiency &eegr;OO does not exceed 5%. A display device using the above hologram is structured by a display unit for generating a signal light; a hologram screen formed by either reflection or transmission hologram, and a projecting unit for projecting the signal light to the hologram screen. According to the present invention, it is possible to easily produce a hologram, for example, a screen hologram, having no cloudiness or cloudy state when an observer observes an image displayed on the screen, and to a display device using the above hologram screen.

    摘要: An optical pickup includes: an objective lens that collects a first beam and a second beam and emits the first and second beam toward an optical information recording medium on which information can be recorded as a recording mark as a result of being exposed to the first beam; a section that drives the objective lens to focus the second beam on a reflection layer formed on the optical information recording medium, the reflection layer at least partly reflecting the second beam; and a section that changes the convergence state of the first beam to position a focal point of the first beam a distance away from a focal point of the second beam in the direction of depth in order to place the focal point of the first beam at a target depth.

    摘要: A duplicating photosensitive material film is brought into close contact with an ND glass reduced in thickness so as to become flexible or a flexible sheet or an ND glass coated with a cushioning layer through an optical contacting liquid containing a surface active agent. In addition, a spacer is interposed between a hologram original plate and a duplicating photosensitive material, and a space defined by the spacer is filled with an optical contacting liquid, thereby regulating the thickness of the optical contacting liquid layer with the spacer. Therefore, when pressure is applied, the optical contacting liquid is uniformly pressed, so that it can be made uniform and thin in thickness. Accordingly, it is possible to prevent a failure of duplication of a hologram image due to undesirable flow of the optical contacting liquid. In addition, the wettability of the optical contacting liquid improves, so that it is possible to prevent trapping of air and foaming and to make the optical contacting liquid uniform and thin in thickness. Thus, it becomes possible to duplicate a hologram image excellently. In addition, a cushioning layer is provided on the inner side of an AR coated ND glass or on the upper side of a photosensitive material film, and another cushioning layer is provided on the side of an original plate protecting glass which is closer to the optical contacting liquid or on the lower side of the photosensitive material film. With this arrangement, even if dust enters, it can be effectively held inside the cushioning layers. Thus, it is possible to prevent undesirable flow of the optical contacting liquid and lifting of the film due to dust and hence possible to perform duplication effectively without any hindrance. Also disclosed is a hologram producing apparatus which includes mechanisms for feeding and taking up a duplicating photosensitive material film, and a contacting liquid dropping mechanism. The apparatus further includes a mechanism for nipping an excess of contacting liquid dropped, a mechanism for drying the contacting liquid attached to the exposed duplicating photosensitive material film, a mechanism for positioning the film, etc.
