A method of driving and sensing a resonant sensor network wherein a least a one resonant sensor is driven by a first light from a first light source at a first frequency, wherein said first light source is modulated by an a.c. source. A second light source at a second frequency is utilized sense...http://www.google.com.hk/patents/US5844236?utm_source=gb-gplus-share專利 US5844236 - Multi-wavelength optical drive/sense readout for resonant microstructures
