Paper Abstract

Angular Domain Spectroscopic Imaging employs an array of micro-channels to perform angular filtering of light that traverses a turbid sample to reject moderately to highly scattered light. In this work, we experimentally characterized an ADSI system by measuring transmission spectra and the first and second derivatives obtained from absorbing and scattering targets. The derivative analysis was used to estimate the concentration of indocyanine green mixed in a scattering liquid. The experimental results provided support for ADSI as a potential method for quantitative spectroscopic imaging of ex vivo tissue samples.
