1. An imaging system comprising:
a scattering assembly, the scattering assembly comprising:
a scattering medium positioned a first distance from an object to be imaged, the scattering medium comprising a plurality of particles suspended in a suspension medium; and
at least one field source generating an electromagnetic field to manipulate the plurality of particles;
a detector comprising a plurality of detector elements positioned a second distance from the scattering medium;
an image processing system configured to reconstruct an image of the object from an object image signal generated by the detector using object light scattered by the scattering medium and incident on the detector, and
an illumination optical system, the illumination optical system comprising:
an object subsystem having the object positioned therein;
a point illumination subsystem comprising a point illumination light source emitting the point illumination light; and
an optical element combining the object subsystem and the point illumination subsystem,
wherein: the object light from the object propagates through the object subsystem to a location on the optical element and the point illumination light propagates through the point illumination subsystem to the location on the optical element, and
the location is separated from the scattering assembly by the first distance in the light propagation direction.
