Abstract

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.
