description An optical ratio scale-based water quality measurement device according to the present invention comprises: a detection fluorescent dye that selectively reacts with a detection target material and changes the wavelength of fluorescence; a sensor film to which a reference fluorescent dye that does not react with the detection target material is fixed; a detection fluorescent dye and the reference fluorescent dye react to the light source, respectively, and the detection reaction light; a light source unit irradiating light toward the sensor film to generate a reference reaction light; a lens unit installed between the light source unit and the sensor film to guide the light source of the light source unit to the sensor film, and guiding the detection reaction light and the reference reaction light generated by the sensor film; a beam splitter installed to face the sensor film with the lens unit interposed therebetween to separate the detection reaction light and the reference reaction light guided by the lens unit; a detection photodetector configured to detect the detection reaction light separated by the beam splitter; a reference photodetector for detecting the reference reaction light separated by the beam splitter; and a calculation unit for calculating a concentration of a detection target material based on a ratio scale of fluorescence intensity of the detection reaction light to the reference reaction light. As described above, by using an optical ratio scale-based water quality measurement device according to the present invention, the present invention has the advantage of being able to provide a water quality measurement device with excellent reliability and stability as a low-cost entry-level type. 본 발명에 따른 광학식 비율 척도 기반 수질측정장치는 검출대상물질과 선택적으로 반응하여 형광의 파장이 변화하는 검출 형광염료와, 상기 검출대상물질과 반응하지 않는 기준 형광염료가 고정된 센서막과; 상기 검출 형광염료와 기준 형광염료가 광원에 각각 반응하여 검출 반응광, 기준 반응광을 생성할 수 있도록 상기 센서막을 향해 빛을 조사하는 광원부와; 상기 광원부와 상기 센서막 사이에 설치되어 상기 광원부의 광원을 상기 센서막에 안내하고, 상기 센서막에서 생성된 검출 반응광과 기준 반응광을 안내하는 렌즈부와; 상기 렌즈부를 사이에 두고 상기 센서막과 대향 설치되어 상기 렌즈부에 의해 안내되는 검출 반응광과 기준 반응광을 분리하는 빔 스플리터와; 상기 빔 스플리터에 의해 분리된 검출 반응광을 검출하는 검출용 광검출기와; 상기 빔 스플리터에 의해 분리된 기준 반응광을 검출하는 기준용 광검출기와; 기준 반응광 대비 검출 반응광의 형광 세기 비율 척도 기반으로 검출대상물질의 농도를 산출하는 산출부;를 포함한다. 이와 같이 본 발명에 따른 광학식 비율 척도 기반 수질측정장치를 이용하면, 저가 보급형으로 신뢰성 및 안정성이 우수한 수질측정장치를 제공할 수 있는 장점이 있다.
