Micro optical sensor device
First Claim
1. A sensor device for measuring a concentration of a substance within a sample comprising:
- a sensor comprising an optical transmission member having a first end and a second end, the second end having a tip portion attached thereto and an active material incorporated within the tip portion, the tip portion adapted to be inserted into a sample, the active material capable of interacting with a substance within a sample;
a light source coupled to the first end of the sensor for emitting a beam of light into and through the sensor and into a sample, the emitted beam of light having a wavelength and the active material interacting with a substance within a sample to change the wavelength of the emitted beam of light to produce a reflected beam of light and the sensor for transmitting the reflected beam of light out of the second end thereof, means for receiving the reflected beam of light from the second end of the sensor for producing a signal indicative of the reflected beam of light; and
a processor for receiving the signal indicative of the reflected beam of light and for processing the signal to determine the concentration of a substance within a sample.
