Abstract

Current broadband hyperspectral imaging systems typically require 2 or more camera types (e.g. Si, InGaAs) to achieve high sensitivity in the wavelength range of 400 – 1700 nm. Given the tissue contrast available in this range, creating a compact real-time imaging system that could be deployed in the clinic would be advantageous. Here, we used a state-of-the-art camera based on the Sony SenSWIR image sensor that displays high sensitivity across the VIS-NIR-SWIR to create a broadband hyperspectral imaging system. After camera calibration, we acquired broadband spectra from patient specimens, demonstrating the ability to collect high quality spectra from biological tissues.
