Nut and Fabric Sorting Techniques

The video tutorial addresses a common question from industrial customers about the proper wavelength range for sorting samples. It presents two methods to determine this: consulting literature or conducting test measurements. The tutorial demonstrates sorting using the FX17 device, focusing on two sample types: fabrics and nuts. For fabrics, the video shows how to distinguish between polyester, cotton, and wool using spectral analysis. For nuts, it demonstrates separating nut meat from shells, highlighting the use of normalization and first derivative techniques to enhance spectral differences.

What are the two methods suggested for determining the proper wavelength range for sorting samples?

• Guessing and checking with random samples
