Abstract

Spectral and temporal profiles together with polarization for far-red to NIR emission wing beyond 650 nm were measured form adipose and tissues. The characteristics of the emission arising form adipose and tissues are shown to be different under 532 nm and 632 nm laser excitation indicating a different origin of the emission. The difference in the spectral intensity of the far-red to NIR emission under 632 nm laser excitation was used to image and distinguish adipose from tissue.
