Abstract

Provided are a method and/or apparatus for measuring the concentration of a detection target using the transmission or reflection of light. The system includes an illumination unit disposed over a biodisc and configured to apply light to the detection target included in the biodisc and a camera module disposed below the biodisc and configured to measure the amount of light transmitted through the detection target.

Claims

1. A system for measuring a concentration of a detection target using the transmission of light, the system comprising:

an illumination unit disposed over a biodisc and configured to apply light to the detection target included in the biodisc;

a camera module disposed below the biodisc and configured to measure an amount of the light applied by the illumination unit that is transmitted through the detection target;

a concentration determining unit configured to determine the concentration of the detection target based on the measured amount of the light transmitted through the detection target; and

a first feeding system having a first feeding motor to move the camera module in a diametral direction of the biodisc.

2. The system of claim 1, further comprising a printed circuit board (PCB) disposed below the biodisc,

wherein the camera module is disposed on the PCB.

3. The system of claim 1, further comprising a PCB having a hole disposed below the biodisc,

wherein the camera module is disposed below the hole of the PCB.

4. The system of claim 1, wherein a plurality of illumination units are arranged a predetermined distance apart from one another in a diametral direction of the biodisc, and wherein a first illumination unit is used to measure the concentration of the detection target and a second illumination unit is used to measure a concentration of a second detection target.

5. The system of claim 1, wherein the illumination unit moves in a diametral direction of the biodisc and applies the light to the detection target disposed in a predetermined position,

wherein the camera module moves in the diametral direction of the biodisc and measures the concentration of the detection target disposed in the predetermined position.

6. The system of claim 2, wherein the illumination unit and the camera module unit move separately relative to the PCB.

7. The system of claim 1, further comprising:

a second feeding system having a second feeding motor, a second mechanism, a second supporting unit to move the illumination unit to move in a diametral direction of the biodisc and to move separately from the camera module.

8. The system of claim 4, the camera module moves in the diamentral direction of the biodisc and measures the concentration of the detection target disposed in a predetermined position.

10. The system of claim 1, the first feeding system further comprising:

a first mechanism configured to fix the camera module.

11. The system of claim 10, the first feeding system further comprising:

a first supporting unit configured to be connected to the first feeding motor and the first mechanism.

9. A method of measuring a concentration of a detection target using the transmission or reflection of light, the method comprising:

applying light to the detection target in a biodisc using a predetermined light source;

measuring an amount of the light transmitted through or reflected by the detection target in the biodisc;

determining the concentration of the detection target based on the measuring of the amount of the light transmitted through or reflected by the detection target; and

moving a camera module, which measures the amount of the light transmitted through or reflected by the detection target in the biodisc, in a diametral direction of the biodisc.

12. A system for measuring a concentration of a detection target using the transmission of light, the system comprising:

an illumination unit disposed over a biodisc and configured to apply light to the detection target included in the biodisc;

a camera module disposed below the biodisc and configured to measure an amount of the light applied by the illumination unit that is transmitted through the detection target;

a concentration determining unit configured to determine the concentration of the detection target based on the measured amount of the light transmitted through the detection target; and

a second feeding system having a second feeding motor to move the illumination unit in a diametral direction of the biodisc and to move separately from the camera module.

13. The system of claim 12, the second feeding system further comprising:

a second mechanism configured to fix the illumination unit.

14. The system of claim 12, the second feeding system further comprising:

a second supporting unit configured to be connected to the second feeding motor and the second mechanism.
