<p>A method of driving and sensing a resonant sensor network wherein at least 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 the resonant frequency of the at least one resonant sensor. Wherein said at least one resonant sensor modulates said second light source. The modulated light is provided to a photo detector and the first light source is filtered out of said reflected light. The detector a.c. amplifies the filtered reflected light, thereby detecting said resonant frequency of the resonant sensor.</p> |
