The incident angle of input keeps identical, does not enter from the light of switching fiber exit in output optical fibre, in the present embodiment, if
Surely Exit positions when switching optical fiber does not apply acoustic signals are eye point A.I.e. from the transmission for the light for switching fiber exit
Direction, transmission direction when switching light is entered with the light is identical, from the light of fiber exit is switched relative to incidence
Light is vertically translated, and shooting angle keeps consistent with incident angle.
When applying acoustic signals 104 to switching optical fiber 102, switch the light in optical fiber and deflect and be injected into output
Outwards projected by output optical fibre in optical fiber.By applying the acoustic signals of certain frequency to switching optical fiber, change light and switching
Original transmission direction in optical fiber, makes light deflect so that light enter in output optical fibre from the output optical fibre to
Outer injection.So as to by the applications of acoustic signals whether, change the signal of output optical fibre, the signal can be set to " 0 " and " 1 ".
