    摘要: The present invention relates to a photoelectrical feedback sensing system. A first light signal passes through the sensing apparatus. A second light signal corresponding to a characteristic of a sample within the sensing apparatus is outputted from the sensing apparatus. The first photo detector receives the first light signal and outputs a first electric signal corresponding to the intensity of the first light signal. The second photo detector outputs a second electric signal corresponding to the intensity of the second light signal. A driving signal is generated by the micro-processor to drive the light-emitting unit. The micro-processor receives the second electric signal and converts the second electric signal into a digital signal. The feedback circuit modulates the driving signal for maintaining the optical stability of the first light signal so that the sensing system is less affected by environmental temperature fluctuation and noise interferences.

    摘要: The present invention discloses a localized plasmon resonance sensing device and a fiber optic structure. The device comprises an optical fiber and a noble metal nanoparticle layer. The optical fiber has a plurality of notches, and such notches are located on the side surface of the optical fiber. The noble metal nanoparticle layer is located at the notch. As a result, when a light is launched into the optical fiber, a detecting unit can be used to detect a localized plasmon resonance signal which is generated by the interaction between the noble metal nanoparticle layer and the light.

    摘要: The present invention discloses a self-referencing fiber-optic localized plasmon resonance sensing device and a system thereof. The self-referencing fiber-optic localized plasmon resonance sensing device comprises a reference optical fiber, a sensing optical fiber and a carrier. The reference optical fiber is modified with a first noble metal nanoparticle layer, and receives an incident light to generate a first localized plasmon resonance sensor signal. The sensing optical fiber is modified with a second noble metal nanoparticle layer. The second noble metal nanoparticle layer is further modified with a molecular or biological recognition unit, and receives the incident light to generate a second localized plasmon resonance sensor signal. The carrier is used for placement of the reference optical fiber and the sensing optical fiber. A processing unit is allowed to perform referencing on the second localized plasmon resonance sensor signal based on the first localized plasmon resonance sensor signal.
