Abstract

Provided is a liquid sample analysis chip reading system. The reading system includes an analysis chip, a light emitting part, a plurality of light wave-guides, and a light receiving part. The analysis chip includes a plurality of detecting parts. The light emitting part includes three light sources emitting light having wavelengths (or colors) different from each other. The plurality of light wave-guides irradiate the light emitted from the light emitting part onto the plurality of corresponding detecting parts, respectively. The light receiving part includes a plurality of light receiving devices for receiving the light having a specific color reflected from each of the plurality of corresponding detecting parts of the analysis chip. The three light sources are discontinuously controlled to emit light onto the plurality of light wave-guides.
