Holistic research of diffusely reflected light in cellulosic materials

This paper introduces some applications of time-of-flight or time-resolved spectroscopy to cellulosic materials like wood. Time-of-flight or time-resolved spectroscopy uses short pulses of light illumination where a portion of the light is scattered but most of the light propagates through the sample. By using such technique, we could know that the light scattering contribution to near infrared spectra in wood is significant because it is a complex and highly scattering medium due to its cellulosic structure.
