This paper addresses optical super-resolution in the far field. We will describe the use of a novel optical component, which we call the proximity projection grating (PPG), that can provide different intensity patterns for sample illumination. These different illumination patterns allow the optical system to perform various modes of imaging, all are capable of resolution beyond the Abbe diffraction limit. Results will be shown to demonstrate the operations of some of these imaging modes. The potential of the PPG unit will also be discussed.
