Claim 4:
5. An underwater optical communication aiming method using an underwater optical communication aiming apparatus, the method comprising:
finding, by a first underwater optical communication aiming apparatus in which a plurality of acoustic modules is spaced apart from one another at given intervals and disposed around an optical communication module, a direction or distance of a second underwater optical communication aiming apparatus in response to an acoustic signal of the second underwater optical communication aiming apparatus under water;
aiming, by the first underwater optical communication aiming apparatus, a direction of the first underwater optical communication aiming apparatus at the second underwater optical communication aiming apparatus in order to communicate with the second underwater optical communication aiming apparatus found through the plurality of acoustic modules by using a rotation driving unit;
finding, by the second underwater optical communication aiming apparatus, the direction of the first underwater optical communication aiming apparatus in response to an acoustic signal of the first underwater optical communication aiming apparatus so that the first underwater optical communication aiming apparatus and the second underwater optical communication aiming apparatus face each other in order to increase an optical communication reception rate;
aiming, by the second underwater optical communication aiming apparatus, a light source of the second underwater optical communication aiming apparatus at the direction of the first underwater optical communication aiming apparatus in order to communicate with the first underwater optical communication aiming apparatus found through the plurality of acoustic modules by using the rotation driving unit; and
transmitting or receiving, by the first underwater optical communication aiming apparatus, a laser beam by using the optical communication module,
wherein the optical communication module is disposed in a center frame,
a circular frame is spaced apart from the center frame and the plurality of acoustic modules is disposed in the circular frame,
the center frame in which the optical communication module is disposed and the circular frame in which the plurality of acoustic modules is disposed are connected through a plurality of connection frames,
the circular frame is disposed on a side higher than the center frame, and
each of the plurality of connection frames has a given width, reflects a laser beam transmitted by the light source of the second underwater optical communication aiming apparatus, has a given slope, and provides the laser beam transmitted by the light source of the second underwater optical communication aiming apparatus with guidance to the plurality of acoustic modules or the optical communication module.
