3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Seed cotton reflectance reflectancedegreeofseedcotton
The brightness of the reflected light of the seed cotton sample is expressed by Rd.
3.2
Seed cotton yellow depth yelownessdegreeofseedcotton
The intensity of the yellow hue of the seed cotton sample is represented by b.
4 Test principle
The white light beam is incident on the surface of the seed cotton sample at an angle of 45° to the normal of the cotton sample surface, and the surface of the seed cotton sample is measured in the normal direction.
The surface reflects light. Analyze the spectral components and reflectance, and obtain the Rd and b values of the seed cotton sample.
5 Instruments and tools
5.1 Seed cotton color detector.
5.2 Tester calibration board (standard white board and blackboard).
5.3 A box with a side length of 300mm, used to place the seed cotton sample (sample box).
6 Test steps
6.1 Test preparation
6.1.1 Turn on the switch of the detection component, and the preheating is not less than 0.5h.
