    Abstract: Systems, methods, and apparatuses of low-coherence enhanced backscattering spectroscopy are described within this application. One embodiment includes providing incident light comprising at least one spectral component having low coherence, wherein the incident light is to be illuminated on a target object in vivo. An intensity of one or more of at least one spectral component and at least one angular component of backscattering angle of backscattered light is recorded, wherein the backscattered light is to be backscattered from illumination of the incident light on the target object and wherein the backscattering angle is an angle between incident light propagation direction and backscattered light propagation direction. The intensity of the at least one spectral component and the at least one backscattering angle of backscattered light is analyzed, to obtain one or more optical markers of the backscattered light, toward evaluating said properties.

    Abstract: Optical tomography systems that provide light of multiple distinct wavelengths from a plurality of sources are described. The systems direct light into mammalian tissue, and light from the mammalian tissue is collected at a plurality of reception points. Collected light from each reception point is separated according to its wavelength, and received by a photodetector to produce path attenuation signals representing attenuation along paths between the source locations and the reception points. An image construction system generates a tomographic image of the mammalian tissue from the path attenuation signals. One embodiment of an optical imaging system includes an optical coherence tomography-near infrared probe. The systems and methods may utilize a spectral derivative approach that provides insensitivity to the boundary and boundary artifacts in the signal, thereby improving the quality of the reconstructed images.
