Abstract
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.
