Optical analyzer and optical analysis system therefor

An optical analyzer, comprising:

• a main body having a receiving space, a light-transmitting component provided on one side of the main body, and an object-to-be-measured holding device provided in the receiving space;
• a rotating part linked to the object-to-be-measured holding device;
• a light detection device having a solid-state light source emitter and an optical receiver, the solid-state light source emitter having a plurality of light-emitting elements, each the light-emitting element emitting a light with at least one peak emission wavelength and at least one wavelength range, the optical receiver receiving a light emitted from the light-emitting element, and the solid-state light source emitter disposed on another side opposite to a side of the receiving space where the light-transmitting component is disposed, wherein the light is able to pass the light-transmitting component and forms an optical path along a travel pathway between the light-emitting element and the optical receiver, a distance between the light emitted from the light-emitting element and an object-to-be-measured in the object-to-be-measured holding device is at least 5 cm, the light-emitting element is a light emitting diode, a vertical-cavity surface-emitting laser or a laser diode, and the plurality of the light-emitting elements respectively exhibit discontinuous illumination of an on-off frequency, a plurality of the on-off frequencies are the same or different from each other, or the plurality of the on-off frequencies are partially the same or partially different;
• and
• a driving device connected to the rotating part;
• wherein a time interval of the on-off frequency for turning on the light-emitting element is between 0.00001 seconds and 10 seconds, the on-off frequency is between 0.05 time/second and 50000 times/second, and the time interval of the on-off frequency for turning on the light-emitting element is between 0.00001 seconds and 10 seconds.
