水中マイクロスコープの試作とその操作試験結果

抄録

Research and development work on an observational technique for diagnosis and evaluation of coral reef activity is currently underway at JAMSTEC. An underwater microscope has been developed for in situ observation of corals. This paper describes the design specifications, construction, operational tests, and tests results for the underwater microscope. During the tests with the underwater microscope, it was possible to conduct observations of corallites, septas and the tentacles of a polyp. Moreover, by connecting a time-lapse video cassette-recorder, it was also possible to monitor the growth process for algae. It was found that the video cable must be extended for further improvement of operability. However, this would require significant improvements because of resulting sigrlal attenuation and phase delay.
