Abstract
An optical analysis system and an optical analysis method, which simply change driving electric currents of light-emitting units via using a control and process unit, so that a wavelength range and a peak wavelength of an irradiated light generated by each light-emitting unit may be fine-tuned. A plurality of irradiating lights with different wavelength ranges and peak wavelengths are irradiated to the object to be tested in different times, so that merely fewer light-emitting units may be used to improve a detection resolution and a detection accuracy of a spectrum of the object to be tested.
