摘　　要：Improving the functionality of an optical sensor on a prefabricated platform relies heavily on an optical signal conditioning method that actively modulates optical signals.In this work,we present a method for active modulation of an optical sensor response that uses fiber modal interferometers integrated in parallel.Over a broad frequency range of 1 Hz to 1 kHz,the interferometers’technology allows for adjustable amplification,attenuation,and filtering of dynamic signals.The suggested method is also used to enhance the real-time response of an optical fluid flowmeter.In order to keep tabs on different physical fields,the suggested approach promotes the creation of self-conditioning sensing systems.
