Optical analysis system and optical analyzer thereof

An optical analyzer, comprising:

• a solid-state light source emitter comprising a light source, the light source comprising each one of a plurality of light-emitting components emitting a light with at least one peak emission wavelength and at least one wavelength range, a plurality of the light-emitting components are light-emitting diodes, vertical-cavity surface-emitting lasers or laser diodes, and a plurality of the light-emitting components are able to respectively exhibit discontinuous illumination of on-off frequencies, a plurality of the on-off frequencies are the same as each other or different from each other, or a plurality of the on-off frequencies are partially the same or partially different, and the light which is emitted by a plurality of the light-emitting components forms a first light ray and a second light ray, the second light ray forms a detection light ray after passing through a fluid-to-be measured;
• a first optical receiver to receive the first light ray;
• and
• a second optical receiver to receive the detection light ray;
• wherein when the first light ray has a standard light intensity, a light intensity of the second light ray has a specific ratio to the standard light intensity, and a ratio of the detection light ray to the standard light intensity is a standard transmittance ratio of the fluid-to-be measured;
• and when the first light ray has a working light intensity, a light intensity of the second light ray and the working light intensity exhibits the specific ratio, and a ratio of the detection light ray to the working light intensity is a working transmittance ratio of the fluid-to-be measured, and the standard light intensity and the working light intensity are different;
• wherein a comparison result between the standard transmittance ratio and the working transmittance ratio is used to determine a composition change of the fluid-to-be measured.
