Title: WAVEGUIDE FOR SEAFLOOR SEDIMENT LAYER INSPECTING APPARATUS
Abstract:
The present invention relates to a waveguide for a seafloor sediment layer inspecting apparatus, and provides a waveguide including a main body of which the top is open and having an accommodating space therein, wherein the main body comprises: a first coupling part provided at one end of the main body such that a transmitter for transmitting a sound wave signal is coupled thereto; a second coupling part provided at another end thereof corresponding to the first coupling part, such that a receiver for receiving the sound wave signal transmitted through the transmitter is coupled thereto; and an insertion part having a through-hole, which is at a right angle to the line on which the first coupling part and the second coupling part are arranged, such that a piston core in which a seafloor sediment layer sample is contained is penetratively inserted into the through-hole. According to the present invention, the piston core itself, having been collected in a state similar to that of real seafloor sediments, is fixed in the insertion part provided in the waveguide, such that a sound sensor is provided to the piston core inside the waveguide in a noncontact manner when sound characteristics of the seafloor sediments are measured, so as to enable the sound characteristics to be accurately measured without disturbing the state of the seafloor sediments.
