The magnetic oscillographs have hitherto been used generally as the multichannel recorder when the dynamical strains are measured, but they are inconvenient to observe and compare the phenomena directly. In case of the Brown tube, it is difficult to picture many electron guns in one tube, therefore the instruments which have more than two electron guns have not been of practical use.By using the high speed scanner method, the author succeeded to measure the phases, wave forms and amplitudes of five phenomena of ship strain and vibration in direct vision at the same time.This apparatus has been used not only for measuring the strains and vibration of the tests in the experimental room, but also for measuring the strains on the actual ship "Hokuto-maru" in the sea going test for a long time.In this report, the author describes on te outline of the measuring apparatus and the results of its application.
