Abstract: Briefly, embodiments of methods and/or systems for tomographic imaging are disclosed. In an example embodiment, optical measurements may be obtained for at least a portion of an illuminated object at a plurality of focal positions between the illuminated object and an imaging lens and at a plurality of angular orientations. Rotated representations of the optical measurements may be projected onto a coordinate plane in which in-focus and out-of-focus rotated representations of the optical measurements may form a cross-sectional image of the illuminated portion of the object.
