Embodiment
[0032] like figure 1 As shown, the illumination adaptive method based on the portable near-infrared spectrometer in this embodiment includes the following steps:
[0033] Step 101, constructing a portable near-infrared multi-light illumination system;
[0034] In terms of specific implementation, the multi-illumination illumination system is composed of (1+X+Y) near-infrared illumination light sources, and the specific distribution structure is a convergent annular distribution, in which one main light source is located at the center of the annular distribution structure, and X secondary The light sources are distributed in a ring around the main light source, and the Y tertiary light sources are distributed in a ring around the secondary light sources. Since the sampling spot is located in the center of the portable near-infrared spectroscopy device, the light contribution weight of the main light source is the highest, the secondary light source is the second, and the terti...
