In this study we propose a new approach to active illumination multispectral imaging with only one detector per spectral channel. Our setup is characterized by a high signal-to-noise ratio, relatively simple design and high spatial resolution. It can be integrated with multiple continuous or pulse light lasers operating at different wavelengths in the near-and mid-infrared spectral regions. We present a demonstrator which works in two spectral ranges (1550 nm and 2992 nm) with scattered and transmitted light. We provide examples of acquired multispectral images. Finally, we put forward proposals for further development which will allow for the simultaneous acquisition of dozens of spectral channels, with additional improvements of the image resolution and quality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
