1. An imaging system, comprising a light source that emits light to be delivered to a material under evaluation;
- and a receiver that collects both light that is backscattered by features of the material and fluorescent light that is emitted by features of the material, such that separate apparatuses are not needed to collect both the backscattered light and the fluorescent light.

Abstract
Systems and method for performing simultaneous optical coherence tomography and spectroscopy. In one embodiment, a system includes a light source that emits light to be delivered to a material under evaluation, and a receiver that collects both light that is backscattered by features of the material and fluorescent light that is emitted by features of the material. In one embodiment, a method includes simultaneously collecting near-infrared light backscattered by a material under evaluation and fluorescent light emitted by the material under evaluation using a single light detector.

8. An imaging system for simultaneously performing Fourier-domain optical coherence tomography (OCT) and two-photon fluorescence spectroscopy on a material under evaluation, the system comprising:
-
a low-coherence, near-infrared light source that emits high-power, near-infrared light that causes both backscattering of near-infrared light from features in the material and two-photon excitation of features in the material, the two-photon excitation generating fluorescent light; and
a receiver comprising a single light detector that collects both the backscattered near-infrared light and the fluorescent light so as to enable both Fourier-domain OCT and fluorescence spectroscopy. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A method for performing simultaneous optical coherence tomography (OCT) and fluorescence spectroscopy, the method comprising:
-
exposing a material under evaluation to near-infrared light to cause both backscattering of near-infrared light from and two-photon excitation of features of the material, the two-photon excitation resulting in generation of fluorescent light;
collecting the backscattered near-infrared light and the fluorescent light with a single light detector; and
manipulating data output by the light detector. - View Dependent Claims (20, 21)
