Abstract

Due to its advantages and potential, Hyperspectral Imaging (HSI) has been widely used in many fields, including the food industry, astronomy, archeology, forensic medicine, and medical diagnosis. In this work, we report the performance of a spectrum-simulating light source named the Chromatiq Spectral Engine (CSE) to highlight its advantages in the application of hyperspectral imaging. The CSE is powered by a high-brightness Laser-Driven Light Source (LDLS) and high-throughput spectrally programmable light engine. Key parameters examined for the HSI applications include wavelength tunable range, spectral resolution, out-of-band suppression, and the flexibility in spectral manipulation. A comparison between the CSE and popular solutions in HSI applications, including liquid crystal tunable filters (LCTF), is presented regarding key features and specs along with a discussion of application-dependent design for an efficient HSI system. Also discussed is system control for the CSE, which features an easy-to-use interface for system configuration, output characterization, creation and matching of test spectra, and storage of matched spectra to the instrument. An embedded controller is incorporated into the CSE deploying application firmware which allows for easy integration with the camera system for HSI studies.
