    • Methods and systems of neural network demodulation for an optical sensor. An optical sensor may be coupled to a structure and be capable of reflecting a reflected optical signal. A wavelength of the reflected optical signal may be spread based on a strain being applied to the structure. A replication device may receive the reflected optical signal from the optical sensor and produce a plurality of optical signals. A filter may be coupled to the replication device to receive an optical signal from the plurality of optical signals and filter the received optical signal. A detector may receive the filtered optical signal and provide a voltage output proportional to an amount of the filtered optical signal received. A neural network may receive the voltage output and determine the strain on the structure.
    • 光学传感器神经网络解调方法与系统。 光学传感器可以耦合到结构并且能够反射反射的光信号。 反射光信号的波长可以基于施加到结构的应变来扩展。 复制设备可以从光学传感器接收反射的光信号并产生多个光信号。 滤波器可以耦合到复制设备以从多个光信号接收光信号并对接收到的光信号进行滤波。 检测器可以接收经滤波的光信号,并提供与所接收的滤波后的光信号的量成比例的电压输出。 神经网络可以接收电压输出并确定结构上的应变。
