Fourier Domain Microscopic Imaging
We are developing a new method of microscopic imaging using laser interference patterns, which we call Interference Pattern Structured Illumination Imaging (IPSII). This method directly images the object in the Fourier domain, similar to the method used in Magnetic Resonance Imaging (MRI). IPSII is a type of lensless, single pixel imaging. It is not diffraction limited by the size of a lens, and needs only a single light detector (as opposed to an array of detectors such as a CCD sensor in a traditional digital microscope). The potential advantages of IPSII include low cost high resolution and high field of view imaging devices, an absolute resolution limit which is better by a factor of two than the traditional Abbe limit, a unique technique for phase imaging, and imaging in wavelength regimes where traditional microscopy is difficult, such as x-ray or IR regimes.
