Abstract
A spectrum measuring apparatus includes a plurality of light sources configured to emit light of different wavelengths onto an object, based on current at various intensities that is applied to each of the plurality of light sources, a photodetector configured to receive light that is one among reflected from, scattered from, and transmitted into the object onto which the light is emitted, and measure an intensity of the received light, and a processor configured to obtain spectrum of the object, based on the measured intensity of the received light.
Claims15
A spectrum measuring apparatus comprising:
- a plurality of light sources configured to emit light of different wavelengths onto an object, based on current at various intensities that is applied to each of the plurality of light sources;
- a photodetector configured to:
- receive light that is one among reflected from, scattered from, and transmitted into the object onto which the light is emitted;
- and
- measure an intensity of the received light;
- and
- a processor configured to obtain spectrum of the object, based on the measured intensity of the received light.
A spectrum measuring method comprising:
- applying current at various intensities to each of a plurality of light sources to emit light of different wavelengths onto an object;
- receiving, by a photodetector, light that is one among reflected from, scattered from, and transmitted into the object onto which the light is emitted;
- measuring, by the photodetector, an intensity of the received light;
- and
- obtaining spectrum of the object, based on the measured intensity of the received light.
A component analyzing apparatus comprising:
- a spectrum measurer configured to obtain spectrum of an object;
- and
- a first processor configured to analyze a component of the object by analyzing the obtained spectrum of the object,
- wherein the spectrum measurer comprises:
- a plurality of light sources configured to emit light of different wavelengths onto the object, based on current at various intensities that is applied to each of the plurality of light sources;
- a photodetector configured to:
- receive light that is one among reflected from, scattered from, and transmitted into the object onto which the light is emitted;
- and
- measure an intensity of the received light;
- and
- a second processor configured to obtain the spectrum of the object, based on the measured intensity of the received light.
