ABSTRACT:
The present invention provides an apodization mask that narrows the central lobe of an optical image of a point in a focusing system and suppresses the amplitudes of the sidelobes of the image that are within a predetermined radius of the central axis of the sidelobes, thereby improving resolution of point objects that are relatively close together and presenting better images of small objects.
