Abstract

A microscope paradigm, which the authors term the "mirror tunnel microscope" (MTM), is described. The MTM uses a low numerical aperture (NA) lens together with parallel mirrors positioned between the lens plane and the object plane to provide a relatively simple means for digital wide-field microscopy. In MTM, the mirror tunnel acts as a spatial periodic-bandpass filter, which creates low-resolution, bandpassed versions of the object function in the image plane. However, each low-resolution image formed by the MTM carries a unique band of spatial frequencies. Coherent addition of the phase and amplitude of the spatial frequency information contained in each of these low-resolution images enhances the effective NA of the lens without decreasing field of view. To demonstrate the proof of principle, they have utilized a two-mirror MTM to reconstruct an image of a pinhole. Along the axis perpendicular to the mirrors, the image was reconstructed with higher resolution, commensurate with an effective fivefold NA increase. Initial results indicate that MTM is a promising method for wide-field digital microscopy.
