TWO-DIMENSIONAL OPERATION OF A SCANNING OPTICAL MICROSCOPE BY VIBRATING KNIFE-EDGE TOMOGRAPHY

摘要

We analyze and demonstrate a scanning optical imaging system that uses a vibrating knife edge to collect sets of tomographic projection data of two-dimensional objects. Special concerns arising from nonuniform illumination and offset projection data are covered. A tomographic filtered backprojection algorithm is implemented to reconstruct an image from collected projections. implications for near-field scanning optical microscopy and x-ray microscopy are discussed.
