Abstract
An image recording apparatus and an image recording method can be suitably used for preparing a large number of edge-lit type holograms or holographic stereograms in a simple manner by copying. A hologram recording medium 11 is applied onto a principal surface 10a of a light-introducing block for copying 10 and held in contact with a master 15. Then, reference light L equivalent to reproducing light for reproducing the image of the master 15 is introduced into the light-introducing block for copying 10 through an end face thereof 10b.
Claims11
An image recording apparatus for copying image information recorded on a master comprising a holographic stereogram that carries the image information thereon, said image recording apparatus comprising:
- an exposure processing section directing a reference light to strike an end face of a light-transmitting block-shaped optical member, a recording material being laid on said master, said master and said recording material being optically held in contact with said optical member, wherein
- said master is an edge-lit type holographic stereogram;
- said reference light enters said optical member with an angle of incidence that generates a reflected light for reproducing the image information of said master in an edge-lit arrangement;
- said recording material records an edge-lit type holographic stereogram when said reflected light interferes with said reference light;
- and
- said optical member has the same profile as that of an optical member on which the recording material is to be attached after the image information is recorded thereon.
An image recording method for copying image information recorded on a master comprising a holographic stereogram that carries the image information thereon, said image recording method comprising the steps of:
- directing a reference light from an exposure processing section to strike an end face of a light-transmitting block-shaped optical member, a recording material being laid on said master, said master and said recording material being optically held in contact with said optical member;
- wherein
- said master is an edge-lit type holographic stereogram,
- reproducing the image information of said master in an edge-lit arrangement by causing said reference light to enter said optical member at an angle of incidence that generates a reflected reproducing light,
- recording an edge-lit type holographic stereogram on said recording material when said reflected reproducing light interferes with said reference light, and
- wherein said optical member has the same profile as that of an optical member on which the recording material is to be attached after the image information is recorded thereon.
An apparatus for copying image information recorded on a master comprising a holographic stereogram that carries the image information thereon to a recording material, said apparatus comprising:
- a supply section supplying said recording material;
- and
- an exposure processing section performing exposure processing on said recording material to produce an edge-lit type holographic stereogram;
- wherein
- said exposure processing section comprises:
- an arrangement part bringing said recording material that is supplied and said master optically in contact with each other, and bringing them into optical contact with a light-transmitting block-shaped optical member, and
- an optical system directing a reference light to strike an end face of said optical member;
- wherein
- said master is an edge-lit type holographic stereogram;
- said reference light enters said optical member at an angle of incidence that generates a reflected light for reproducing the image information of said master in an edge-lit arrangement;
- said recording material records an edge-lit type holographic stereogram when said reflected light interferes with said reference light;
- and
- said optical member has the same profile as that of an optical member on which the recording material is to be attached after the image information is recorded thereon.
