Spectral Imaging
Spectral imaging
Spectral imaging combines spectroscopy with imaging, two widespread methodologies, thus generating advantages that cannot be obtained separately by imaging or spectroscopy alone. The spectral content of a sample provides important information that cannot be detected by the human eye or by using an ordinary RGB camera. The spectrum is typically a fingerprint of the chemical compound, its environmental conditions, phase and geometry. Thus measuring the spectrum at each point of a sample is important for a large range of applications from art preservation through forensics to pathological analysis of a tissue section.
