Abstract
There is provided a portable measuring system having a biophotonic sensor. The portable measuring system also includes a tunable light source, an output intensity detector and an output wavelength detector, which are mounted therein. The portable measuring system can precisely measure a variation in the reflectivity spectrum and/or the transmittance spectrum of the biophotonic sensor before and after an antigen-antibody reaction by varying the wavelength of the tunable light source. Thus, the concentration of the antigen is precisely measured.
Claims16
A portable measuring system having a biophotonic sensor comprising:
- a light provider configured to emit light;
- a first optical splitter configured to split the light emitted from the light provider into first and second paths;
- an output intensity detector configured to detect an output intensity of the light on the first path;
- a second optical splitter configured to split the light on the second path, into third and fourth paths;
- an output wavelength detector configured to detect an output wavelength of the light on the third path:
- the biophotonic sensor is configured to transmit or reflect the light on the fourth path, wherein the light intensity on the fourth path changes based on an antigen-antibody reaction in the biophotonic sensor;
- a transmittance detector configured to detect an intensity of the light transmitted through the biophotonic sensor;
- and
- a reflectivity detector configured to detect an intensity of the light reflected from the biophotonic sensor,
- wherein the light provider comprises:
- a tunable light source;
- and
- a tunable light source controller configured to control power supplied to the tunable light source based on the output intensity of the light on the first path that is detected by the output intensity detector, and further configured to control an output wavelength of the tunable light source to be uniform based on the output wavelength of the light on the third path that is detected by the output wavelength detector.
