Abstract

The present invention includes an interferometric imaging system including a paraboloid mirror defining an axis and an illumination source adapted to radiate light from an illumination point of an illumination optical fiber at an off-axis portion of the paraboloid mirror. The present invention also includes a reference illumination source adapted to illuminate the surface of an image receiver through a reference optical fiber with a reference beam having a selectable, variable, or predetermined phase with respect to the illumination source. The from the reference illumination source and light from the optical system cooperate to form a phase image of object on the image receiver.
