Description
technical field [0001] The invention relates to the technical field of algae liquid detection. Background technique [0002] In the process of microalgae cultivation, sampling is required to obtain the spectral information and image information of microalgae. Spectrometers and multispectral cameras are two of the most common devices. After the light generated by the visible-near-infrared light source passes through the algae liquid sample, part of the light energy is absorbed by the sample molecules, and the change of the incident light intensity is measured. After conversion, the spectral information data such as absorbance can be obtained. The light from the 470nm excitation light source irradiates the algae liquid sample in the fluorescence pool, part of the light energy is absorbed by the sample molecules, the sample molecules are excited to emit fluorescence, and the intensity of the emitted fluorescence is detected in a direction that forms a certain angle with the in...
