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.
