Abstract
An optical tomographic system wherein the localization of secondary emitters within an object of interest is determined using the temporal signatures of secondary emission arising from the object being illuminated by an external primary source beam that is non-parallel, such as a cone beam, while the object is moving relative to said beam in a controlled manner. A unique set of secondary emitter spots is localized within the object and, when combined with a computed 3D reconstruction of the object from its primary cone beam projections, creates an image of the secondary emitters in the object so as to enable quantitative three-dimensional imaging of fluorescent labeled molecular probes in a biological cell, for example.
