Creating A Spectral Library Of Food Samples Through Spectroscopic Device Integration With ENVI Software

Abstract

Spectroscopic instruments are essential for determining the spectral signatures of different materials, which offer important information about the distinctive properties of each material's electromagnetic radiation at different wavelengths. Spectral signatures are unique means of identifying materials by their energy patterns that are absorbed, emitted, or reflected. We used the 350–2500 nanometre spectral range ASD FieldSpec4 Standard Spectroradiometer and accompanying software tools for our investigation. Our work focuses on gathering sample spectral signatures to create an extensive spectral library. By utilizing the features of the ENVI 5.5 application software, we were able to develop a reliable Spectral Library for the characterization and analysis of food samples by methodically compiling and organizing the spectral data that came from the spectroradiometer.
