Paper Abstract

The paper gives an overview for laser-interference ultralow-frequency hydrophone designed on basis of unequal-armed Michelson's interferometer using frequency-stabilized laser LGN-303. A circle diaphragm having mirror reflecting surface is used as a reflector. For outboard pressure compensation special cell that equalizes intrinsic and ambient pressure is designed. Some data obtained by laser strainmeter and hydrophone are analysed.
