The light emitting units can be respectively provided with current densities, so that the light emitted by each of the light emitting unit has a light intensity, wherein the current densities are different from each other, or partial of the current densities are different from each other. A number of the light emitting units can be larger than or equal to four, all of the four lighting frequencies of the four light emitting units are different from each other, or partial of the four lighting frequencies of the four light emitting units are identical to each other, and the light emitting apparatus and the object under test rotate relative to each other. A light emitting method, a spectrum detection method and a lighting correction method are also illustrated for increasing SNR, correcting the light intensity or the spectrum signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light emitting apparatus, light emitting method, light detection apparatus, spectrum detection method and lighting correction method","description":"A light emitting apparatus has light emitting units.
