Abstract

There is provided a method and a system for collecting optical data for use in time resolved optical imaging wherein excitation light of a tunable wavelength is directionally propagated to impinge on a plurality of illumination points at the surface of a region of interest in a turbid media, comprising for example a biological tissue such as that comprised in small animals or in human organs. Light re-emitted with a different wavelength from a fluorescent marker present in the tissue is collected and directionally propagated towards a detector. A filter located in a path of the light rejects photons outside a fluorescence emission spectrum of the fluorescent marker while maintaining selectivity of the re-emitted light. The detector produces time resolved optical signals useful for optical image reconstructions.
