Real-time edge detection by cyclic-path polarization interferometer

Issue: 4
Pages: 727 - 730
In a triangular path cyclic interferometer employing a polarizing beam splitter (PBS), the two counter-propagating beams are orthogonally polarized. A sample placed almost equidistant from the PBS is imaged by a lens placed in the path of the emerging beams so that two defocused images of the sample are recorded on a CCD. Using a linear polarizer in the path of the orthogonally polarized imaging beams, it is possible to achieve amplitude subtraction between the two images, resulting in an edge-enhanced image of the sample. The proposed real-time edge-enhancement technique is experimentally demonstrated. © 2014 Optical Society of America.
