We present proof of principle experiments for a single pixel [1] optical imaging method which should be capable of resolutions up to twice the normal Abbe diffraction limit (similar to other structured illumination techniques [2,3]), does not require any expensive high numerical aperture lenses, and does not need any optics to be placed close to the imaged object. This method, which we call Interference Pattern Structured Illumination Imaging (or IPSII), naturally combines high field of view with high resolution at low cost, making it potentially well suited for low cost medical or scientific analysis instruments. Because it requires only a single pixel detector, it may also be well suited to imaging in extreme wavelength regimes (such as ultraviolet, x-ray or the far infrared) where lenses or highresolution imaging arrays are difficult to manufacture.
