Abstract

This paper presents novel imaging measurements of imapact fluid pressure by using bioluminescent dinoflagellates. Uncertainities of the bioluminescent responses for the pressure due to circardian biological rhythm and variation of activity were identified experimentaly. It has been found that the bioluminescence inteisity linearly correlates with the impact pressure in the range less than 1200kPa, and the maximum pressure acting on the wall in the water drop test was reasonably estimated by the present bioluminscent imaging. The emperical formula describing the time variation of the bioluminescent inteinsity under the impact pressure was also proposed in this paper.
