Abstract

We explored the depth penetration in tissue-mimicking intralipid-based phantoms in SWIR (800-1650 nm) using a hyperspectral imaging system composed from a 2D CCD camera coupled to a microscope. Hyperspectral images in transmission and reflection geometries were collected with a spectral resolution of 5.27 nm and a total acquisition time of 3 minutes or less that minimized artifacts from sample drying. Michelson spatial contrast was used as a metric to evaluate light penetration. Results from both transmission and reflection geometries consistently revealed the highest spatial contrast in the wavelength range of 1300 to 1350 nm.
