Abstract

The characteristics of the far-red and near-infrared (NIR) emission beyond 650 nm from breast human and chicken tissue samples were investigated under 532 and 632 nm low intensity laser excitation. The intensity, spectral, polarization and temporal differences of the emission are observed for different types of tissues. The differences of the far-red emission spectral wing under 2 eV photo-excitation were utilized to image different tissue components in human and animal tissue samples.
