Claim Text:
1. A microscopy instrument comprising: a splitter to receive a monochromatic beam of light and split the beam into at least three separate coherent beams; an illumination phase control including at least one rotatable window, the at least one rotatable window configured to apply at least one phase shift to at least one of the at least three separate coherent beams; an objective lens to focus the at least three separate coherent beams to form an interference pattern, wherein the illumination phase control is configured to change a position of the interference pattern with the at least one rotatable window to be rotated with respect to at least one path of the at least three separate coherent beams; and an illumination pattern rotator disposed between the illumination phase control and the objective lens, the illumination pattern rotator to rotate the at least three separate coherent beams output from the illumination phase control, which results in the interference pattern to be rotated through the same angle.
