摘要： PROBLEM TO BE SOLVED: To provide a device and a method for manufacturing a hologram with a small-size and low-cost structure of the device without causing problems of vibration. SOLUTION: Pulsed laser light is repeatedly emitted from a light source 10 driven by a pulsed current and the laser light emitting from the light source 10 is branched into two beams by a half mirror 20. The laser light reflected by the half mirror 20 is spatially modulated by a spatial optical modulating element 36 and the modulated laser light is made incident on a local region on a photosensitive material 2 as object light. Also, laser light passed through the half mirror 20 is made incident on the local region on the photosensitive material 2 as reference light. The photosensitive material 2 is relatively moved in the direction parallel to the plane of the photosensitive material 2 with respect to the object light optical system and the referential light optical system which the laser light is not emitted from the light source 10 so that the object light and the reference light enter the local region where an element hologram is to be formed next in the photosensitive material 2.

SOLUTION: As for thp holographic stereogram forming device, laser beam outputted from a laser beam source 11 is branched into two ways by a half mirror 12, one is object light L1, the other is reference light L21.

The reference light transmitted through the photoreceptive material 50 is reflected by a mirror 32, and the photoreceptive material 50 is irradiated with the reflected reference light L21 again. As for the reference light L21 made incident from the mirror 31 and the reference light L22 made incident from the mirror 32, the light L21 is made incident on one side of the photoreceptive material 50, the light L22 is made incident on the other side of the material 50, and the light L21 is parallel to the light L22.

摘要： PROBLEM TO BE SOLVED: To make it possible to form a Lippmann type hologram with which a color reconstructed image suppressed in color shift and distortion is obtainable with a white illumination light by using coherence light of a single wavelength by causing the interference of the object light and reference light calculated by a specific method on a photosensitive material at the incident angles calculated by a specific method. SOLUTION: The respective incident angles of the reference light and object light for the first direction on the photosensitive material and the respective incident angles of the reference light and object light for the second direction orthogonal therewith are calculated in accordance with the condition equation of the two-dimensional hologram and the condition equation of the three-dimensional hologram (S11 to 13). The incident angle of the object light is so controlled as to deal with the exit angle of the object reconstruction light or the reconstruction object information dealing with the exit angle of the object reconstruction light is converted to the incident object information dealing with the incident angle of the object light (S14). The interference of the object light and the reference light is caused on the photosensitive material at the incident angles calculated in S11 to 13, by which the Lippmann hologram is recorded (S15).

摘要： PROBLEM TO BE SOLVED: To provide a method for producing a hologram by which recording time can be reduced and an optical system for producing the hologram can be small-sized. SOLUTION: In this method for producing the hologram, a diffused screen image is outputted as object light on a first recording surface 12 via a lens 8' at the time of producing a master hologram. At the time of producing a slave hologram, a second recording surface 12" is arranged at an image forming position of the object light by the lens 8'. In this method, distance between the diffused screen 7' and the first recording surface 12 at the time of recording the master hologram 12' and distance between the master hologram 12' and the second recording surface 12" at the time of recording the slave hologram 12" can be made to be different. Accordingly the hologram can be produced by using a small-sized optical system by varying these distances, if necessary.

摘要： PROBLEM TO BE SOLVED: To provide a method for forming a hologram which can decrease noise observed in a reproduced image. SOLUTION: The distance between a spatial optical modulating device 7 and a lens 8 is determined, in such a manner that the position of a real or virtual image 9, 9' (L, L') of the objective light by the lens 8 coincides with the observation position of a hologram 12'. The reproduced image is constant at the observation position L, L', so that even if noise is present in the reproduced image by the spatial optical modulation device 7'; and since the noise itself is present at the observation position at all times and is inconspicuous as noise, the noise is decreased substantially.

The other laser beam halved by the half-mirror 13 is made incident on the region of the photosensitive material 17 corresponding to the transmission region displayed on the liquid crystal panel 16 as a reference beam. The object beam and the reference beam made incident on the photosensitive material 17 are interfered with each other and an element hologram is recorded.

摘要： PROBLEM TO BE SOLVED: To provide a hologram forming device and a method therefor capable of forming a holographic stereogram in a short time. SOLUTION: An image is presented to a spatial optical modulation element 10 corresponding to the position of the local area of photosensitive material 19 regulated by the aperture of a slit 18. Object light emitted from the element 10 successively passes through a lens 11, the aperture of a spatial filter 12, a lens 13, a one-dimensional lens array 14, a lens 15, a lens 16, a cylindrical lens 17 and the aperture of the slit 18, and is made incident on the local area of the material 19 at a specified incident angle after high-order diffracted light is removed. A reference light is made incident on the local area of the material 19 from the rear of the material 19. In the local area of the material 19, the object light and the reference light interfere with each other and an element hologram is recorded. Thereafter, the material 19 is moved in an x-axis direction and the element hologram is similarly recorded in the adjacent local area.

摘要： A pulsed laser beam is repeatedly output from a pulse current driven light source (10), and the laser beam output from this light source (10) is two-branched by a half mirror (20). The laser beam reflected by the half mirror (20) is spatially modulated by a spatial light modulation device (36), and this modulated laser beam is entered into a local region on a photosensitive material (2) as an object light. The laser beam having penetrated through the half mirror (20) is entered into a local region on the photosensitive material (2) as reference light. While a laser beam is not output from the light source (10), the photosensitive material (2) is relatively moved in parallel with the face of the photosensitive material (2) so that the object light and the reference light may enter a next local region on the photosensitive material (2) where a hologram is to be formed.

摘要： In the method for producing holograms, a plurality of images displayed on a spatial optical modulating element 6 is used as the object light. Through a lens array 7 composed of a plurality of lenses disposed corresponding to each of the images, which are included in the object light, and a reducing optical system 9 and 10 for reducing the object light emitted from the lens array 7, the object light is made to irradiate a recording surface 11 along with a reference light; thereby interference light between the object light and the reference light is recorded on the recording surface 11. Between the spatial optical modulating element 6 and the lens array 7, partitions 15 for separating the respective images are provided; thereby noise is reduced.
