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: Spectrographic measurements are often limited by the amount of light that is available. Photons that are not collected or measured reduce the signal to noise and therefore reduce measurement precision. This invention collects the zero order light and sends it through the spectrometer again. In an atmospheric LIDAR, the zero order recycling is estimated to increase the rotational Raman signal by an additional 20%. A grating based spectrometer where the zero order light is collected by a lens or mirror and focused into a fiber optic that sends the light to the input slit where it is directed into the spectrometer again. There can be a plurality of recycle fibers. The detector can be either a single linear array or a two dimensional array such as a CCD or CMOS camera.

Abstract: The invention provides methods and apparatus comprising a multi-wavelength laser source that uses a single unfocused pulse of a low intensity but high power laser over a large sample area to collect Raman scattered collimated light, which is then Rayleigh filtered and focused using a singlet lens into a stacked fiber bundle connected to a customized spectrograph, which separates the individual spectra from the scattered wavelengths using a hybrid diffraction grating for collection onto spectra-specific sections of an array photodetector to measure spectral intensity and thereby identify one or more compounds in the sample.
