Variable Fabrv Perot type interferometer

摘要

Variable interferometer arrangement, which contains a 'Fabry Perot' interferometer, consisting of a pair of reflecting substances (4), which lie opposite to each other across an intervening space. This intermediate space is formed by spacers (3).In addition means are provided to deform at least one of the reflecting surfaces (1,4;2,4), which form the Fabry Perot' interferometer, so that its interferometer characteristics are changed. The spacer (3) consists of a film, which is produced by means of vapour separation, spraying, chemical vapour separation, spin coating or screen printing
