optica briidge circuti

In the optical bridge balance-compensated type fiber-optic bi-directional strain-displacement sensor,the beams emitted by the optical sources are separated to the tension-sensitized fiber and the reference fiber,or the compression-sensitized fiber and the reference fiber.

在光桥平衡补偿型光纤双向应变位移传感器中,光源发出的光被3dB耦合器分束到拉敏光纤和参考光纤或压敏光纤和参考光纤中,而这些调制光和参考光由两光探测器分别进行测量。
