Abstract:
A system for imaging an object located in a highly scattering medium comprising:a) means for illuminating the object located in the highly scattering medium, wherein the light emergent from the highly scattering medium consists of a scattered component and a non-scattered component; andb) a microscope for forming a magnified image of the object using the non-scattered component of the light emergent from the highly scattering medium and a portion of the scattered component of the light emergent from the highly scattering medium, said microscope includingi) objective means for forming an enlarged intermediate image of the object at a back focal plane of said objective means;ii) eyepiece means appropriately positioned relative to said objective means for forming a virtual image of the enlarged intermediate image of the object at image plane of said eyepiece means; andiii) an aperture located at the back focal plane of said objective means for passing the non-scattered component of the light emergent from the illuminated highly scattering medium and for spatially filtering the scattered component of the light emergent from the illuminated highly scattering medium.
