A binary mask is commonly treated as an amplitude transmittance function whose profile can be constructed using the tools of 2-D linear systems theory. We present an alternative approach using mathematical morphology for the digital synthesis of binary diffractive masks formed of elementary nonperiodic, periodic, and annular geometric configurations by means of a small set of structuring elements used as building blocks and the basic operations of dilation, erosion, and the morphological gradient. We apply this new technique in a optical-digital coherent processor that uses a programmable liquid crystal display to visualize the spatial dynamics of Fraunhofer diffraction patterns in real time. © 2001 Society of Photo-Optical Instrumentation Engineers. |
