ABSTRACT:
An interference contrast imaging system images phase objects. The system includes an illumination source, illumination optics, polarizing optics for splitting the illumination into orthogonal polarizations and for recombining the polarizations, objective optics that form an image at a detector, a wavefront coding element and a post processor for processing the image by removing a phase shift imparted by the wavefront coding element. The wavefront coding element has an aperture, is between the phase object and the detector, and provides an altered optical transfer function of the imaging system by imparting the phase shift to the illumination transmitted through the wavefront coding element. The altered optical transfer function is insensitive to an object distance between the phase object and the objective optics over a greater range of object distances than would be provided by an optical transfer function of a corresponding interference contrast imaging system without the wavefront coding element.
