WebThe index introduces dust optical density (α), which can be simply estimated by spectral unmixing, into the normalized difference between reflectance at near-infrared (2.13 μm) and blue (0.469 μm). Dust severity can thus be rated from weak to severe within a standard range of –1 to 1. WebJul 29, 2024 · The dust count is represented by Dust Index (DI), which is an indication for the total dust count per area of product. Generally, softer and consequently weaker products have higher propensity to release dust and lint particles as it can be seen from the figures. Dusting and linting issues can potentially occur with a dust index greater than 100.
