  • Sensing system having wavelength reflectors that receive modulated light signals
    Patent number: 7697121
    Abstract: The sensing system includes a plurality of modulators that are each configured to modulate a different light signal. The sensing system also includes optical pathways that transport the modulated light signals to one or more wavelength reflectors. Each wavelength reflector is configured to reflect a portion of the modulated light signals at a characteristic wavelength that is a function of an influence external to the wavelength reflector. The sensing system also includes a light sensor configured to receive the reflected light signals and to output a modulated electrical signal that is a function of the power of each of the reflected light signals. The sensing system can also include electronics configured to employ the modulated electrical signal so as to determine one or more results selected from a group consisting of: the characteristic wavelength of one or more of the wavelength reflectors and a level of the external influence on one or more of the wavelength reflectors.
