| titleOfInvention | Method and apparatus for using optical modulation to improve signal-to-noise ratio in silicon nanowire sensor |
| abstract | Provided in the present invention are a method and an apparatus for using optical modulation to improve the signal-to-noise ratio in a silicon nanowire sensor. The method comprises: on the basis of a carrier wave signal, determining an optical excitation signal for a silicon nanowire sensor; on the basis of the optical excitation signal, acquiring a modulated signal of the silicon nanowire sensor on an object being sensed; and using a lock-in amplifier to process the carrier wave signal and the modulated signal to obtain a target response signal of the silicon nanowire sensor on the object being sensed. In the method of the present invention, a lock-in amplifier is used to transpose the signal spectrum of a target response signal of a silicon nanowire sensor to the frequency of a carrier wave signal, and then amplification is performed, avoiding interference from noise in the silicon nanowire sensor. The signal-to-noise ratio in the silicon nanowire sensor can thus be greatly improved, enhancing the anti-interference capacity of the sensor. |
