Abstract :
Calculations of circumferential strain, polar and equatorial displacement, lowest natural frequency, buckling pressure, and optical pressure sensitivity for an oblate-spheroidal-shell fiber optic hydrophone are presented using the theory for thin shells. Sample designs based on these calculations are compared to other fiber-optic hydrophone designs of similar dimensions and materials. A prolate-spheroidal-shell hydrophone design is also presented
