Optical imaging system's resolution increasing method for e.g. microscope, involves transforming distribution of field of radiation in pupil into plane so that image of object is obtained with resolution that is larger than given resolution
The method involves illuminating an object (8) in different lighting modes and imaging the object by utilizing a projection lens (3) in an image plane. Distribution of an electrical field of radiation is determined, where the field is distributed when imaging is performed in a pupil (12). A complex pupil image is computationally framed for determining distribution of the field of radiation in a virtual pupil. The distribution in the virtual pupil is computationally transformed into the plane, so that an image of the object is obtained with a resolution that is larger than given resolution. An independent claim is also included for a device for increasing resolution of an optical imaging system.
