    Abstract: PROBLEM TO BE SOLVED: To measure the volume change of a liquid with consistency by confining a layer of a liquid with consistency in a part of a rigid body, applying a physical or chemical process, and measuring a linear deviation on the surface to be formed. SOLUTION: A layer of consistency liquid 101 is confined in a vessel 104 of a rigid body 100. After the consistency liquid layer comprising a flat surface is confined in the vessel 104, a probe is equilibrated on a layer of the consistency liquid 101. Normally the prove is equilibrated on the surface of layer of the consistency liquid 101 so that the axis at a tip end is vertical to the surface of consistency liquid layer under a force about 10 mg or less. After equilibrium, the thickness of a consistency liquid layer is acquired and the thickness is acquired relative to the bottom surface of vessel. After the thickness of consistency liquid layer is acquired, the consistency liquid is at least partially allowed to react by an arbitrary method such as exposure to light, heat, etc. As reacted, the surface of consistency liquid layer and the probe tip end contacting it are deviated in the direction vertical to the layer surface. The deviation is a measurement for linear deviation as the consistency liquid react. Then the voluminal change of a consistency liquid which partially reacted is acquired as a function of a linear deviation for the consistency liquid layer.

    Abstract: PROBLEM TO BE SOLVED: To substantially prevent the both of the mutual reaction of optically active monomers and a matrix precursor during hardening and the inhibition of the following polymn. of the monomers by making a matrix polymer and a polymer produced from the polymn. of the one kind of plural optically active monomers compatible with each other. SOLUTION: This optical product is composed of a three-dimensionally crosslinked polymer matrix and one kind of plural optically active monomers and makes at least the one kind optically active monomer contain a part which is substantially independent of the polymer matrix other than a monomer functional group. Then, the matrix polymer and a polymer produced from the polymn. of the one or plural optically active monomers are made compatible with each other. A polymn. reaction carefully considered for the formation of the matrix polymer is, e.g. cationic epoxy polymn. cationic vinyl ether polymn., cationic alkenyl ether polymn. cationic allene ether polymn. or cationic ketene acetal polymn.

    Abstract: PROBLEM TO BE SOLVED: To provide holographic techniques which use a photosensitive polymer medium. SOLUTION: The storage life of a photosensitive polymer medium is improved by sealing the polymer between glass plates. The hermetic seal is designed in such a manner that a material having high Tg or solder can be used as a sealant without damaging the polymer preliminarily held between the plates. The hermetic seal consists of metal foils attached to a plate having extended edges like tabs. The foils are attached prior to supplying the polymer to the assembly. After supplying the polymer, the foils in the outer edge part of the tabs are sealed by local heating apart from the position of the polymer or press-bonded by using mechanical pressing.

    Abstract: PROBLEM TO BE SOLVED: To embody a photopolymer recording medium which is satisfactorily usable with a phase correlation multiplex holography, has usable high quality and is low in scattering. SOLUTION: A photopolymer recording medium 1 consists of an active layer 2 of the refractive index changing with radiation (for example, visible light). This active layer 2 includes a polymer matrix material acting as a host to a photochemical monomer material which responds with the radiation by photopolymn. This matrix material is formed by in-situ polymn. of a multifunctional oligomer having a mol.wt. of >=1000 during precuring. At least 70wt.% of the entire monomer material is monofunctional. The active layer 2 is held by two sheets of supporting plates 3 and 4 and at least one of these supporting plates is transmissive to the radiation. In this embodiment, the monofunctional monomer has an acrylate functional group and its mol.wt. is

    Abstract: An improved recording medium is provided having a rigid porous matrix containing a photoimageable system. In contrast to previous media containing porous matrices, the invention allows readable holograms to be written in a medium without the need for solvent processing steps subsequent to irradiation. Due to the rigid nature of the matrix, polymerization and/or diffusion during formation of each individual hologram induces only a small level of Bragg detuning. Temperature fluctuations similarly induce only a small Bragg shift. Improved archival life of recorded holograms and improved fidelity of read-out, as well as improved optical elements, are thereby attained. And the avoidance of solvent processing makes the process of recording holograms far easier than in previous porous matrix-based media.
