METHOD OF USING A MICRO OPTICAL SENSOR DEVICE
First Claim
1. A method of using a sensor device for measuring a concentration of a substance within a sample comprising the steps of:
- inserting a tip portion of a sensor into a sample, the sensor comprising an optical transmission member having a first end and a second end, the second end having the tip portion attached thereto and an active material incorporated within the tip portion, the active material capable of interacting with a substance within the sample;
emitting a beam of light into the first end of the sensor, through the optical transmission member and the tip portion and into the sample, the beam of light having a first wavelength;
producing a reflected beam of light from the interaction of the active material with the substance within the sample, the reflected beam of light having a second wavelength different from the first wavelength;
receiving the reflected beam of light and producing a signal indicative of the reflected beam of light; and
determining the concentration of the substance within the sample based on the produced signal.

Abstract
A method of using a sensor device for measuring a concentration of a substance within a sample includes inserting a tip portion of a sensor into a sample. The sensor has an optical transmission member having a first end and a second end. The second end has the tip portion attached thereto and an active material incorporated within the tip portion. The active material is capable of interacting with a substance within the sample. The method includes producing a reflected beam of light from the interaction of the active material with the substance within the sample, the reflective beam of light having a second wavelength different from the first wavelength. The method includes determining the concentration of the substance based on the reflected beam of light.

reflecting a second reflected beam of light off of the second active material, the second reflected beam of light having a third wavelength different from the first wavelength of the emitted beam of light and the second wavelength of the first reflected beam of light, the second reflected beam of light relating to a concentration of the second substance within the sample;
detecting the first and second reflected beams of light; and
determining a concentration of the first substance within the sample from the first detected reflected beam of light, and a concentration of the second substance within the sample from the second detected reflected beam of light.
