摘要
(US20160259156) Embodiments of the invention provide an imaging system and method using adaptive optics and optimization algorithms for imaging through highly scattering media in oil reservoir applications and lab-based petroleum research.  Two-/multi-photon fluorescence microscopy is used in conjunction with adaptive optics for enhanced imaging and detection capabilities in scattering reservoir media.  Advanced fluorescence techniques are used to allow for super-penetration imaging to compensate for aberrations both in and out of the field of interest, extending the depth at which pore geometry can be imaged within a rock matrix beyond the current capability of confocal microscopy.  The placement of a Deformable Mirror or Spatial Light Modulator for this application, in which scattering and index mismatch are dominant aberrations, is in an optical plane that is conjugate to the pupil plane of the objective lens in the imaging system.  The invention images stationary and dynamic nanoparticles, surfactants, fluid-fluid interfaces and tracers which can be used to study properties such as diffusion, mobility, adhesion, stickiness and wettability within the 3D structure of cores and thin sections.

(US20160259156) What is claimed is: 1.  A laser scanning multi-photon fluorescence microscope system for imaging dynamic and stationary particles, fluorescent molecules, and fluid interfaces in reservoir scattering media, the system comprising: a two/multi-photon laser for generating a laser beam;   a deformable mirror in an optical plane, which is conjugate to the pupil plane of an objective lens, with a segmented light modulator or a continuous mirror surface, for modifying a phase of coherent light of the laser beam focused on a sample;   two pairs of conjugate lenses with two galvanometric scanners in an optical or pupil conjugate plane with the deformable mirror;   a microscope objective with a back pupil where the deformable mirror can image the beam in order to focus the beam and collect a fluorescence signal; and   an image processing device with a digitizer for digitizing the fluorescence signal, processing the collected fluorescence values and displaying the results with a stitched image. 2. The laser scanning system of claim 1, wherein the fluid flow is tracked using an algorithm that allows imaging of individual particles. 3. The laser scanning system of claim 1, wherein the fluid flow is tracked using smaller image windows and faster scan rates than the stationary images. 4. The laser scanning system of claim 1, wherein the effective field of view for a given pattern is extended over the image plane. 5. The laser scanning system of claim 1, wherein the image is optimized at the center allowing for recovery of intensity in a region around the center of the image. 6. The laser scanning system of claim 1, wherein the deformable mirror uses the auto-fluorescence from the scattering media as an optimization source. 7. The laser scanning system of claim 1, wherein the optimization pattern is taken for each location and then stitched together with patterns from other locations to increase the field of view. 8. The laser scanning system of claim 1, wherein the scattering media consists of porous media, rock pieces, rock thin sections, turbid fluids, oil-water mixtures, mineralogical samples, and rock mimics. 9. A laser scanning multi-photon fluorescence microscope method for imaging dynamic and stationary particles, fluorescent molecules, and fluid interfaces in reservoir scattering media, the method comprising the steps of: pulsing a laser to create a two/multi-photon laser beam;   expanding the beam with two pairs of conjugate lenses in an optical conjugate plane with two galvanometric mirrors;   filling a deformable mirror aperture with the beam;   modifying the phase of the coherent light of the laser beam focused on the sample with a deformable mirror that is in an optical plane conjugate to the pupil plane of an objective lens;   focusing the beam and collecting a fluorescence signal from the sample with a microscope objective;   digitizing the fluorescence signal;   processing the collected fluorescence values; and   displaying the results with a stitched image with an image processor and a display device. 10. The laser scanning method of claim 8, further including the step of tracking the fluid flow using an algorithm that allows imaging of individual particles. 11. The laser scanning system of claim 8, further including the step of tracking fluid flow using smaller image windows and faster scan rates than the stationary images. 12. The laser scanning system of claim 8, further including the step of extending the effective field of view for a given pattern over the image plane. 13. The laser scanning system of claim 8, further including the step of optimizing the image at the center allowing for recovery of intensity in a region around the center of the image. 14. The laser scanning system of claim 8, further including the step of using the auto-fluorescence from the scattering media as an optimization source. 15. The laser scanning system of claim 8, further including the step of applying the optimization pattern to each location and then stitching together the optimization patterns from other locations to increase the field of view. 16. The laser scanning system of claim 8, further including that the scattering media consists of porous media, rock pieces, rock thin sections, turbid fluids, oil-water mixtures, mineralogical samples, and rock mimics.
