For the past several years, we have been conducting research on hybridsystems that combine nonconventional incoherent optical spatial filtering systems with digital or analog electronics to allow bipolar (and, if desired, complex valued) spatial filtering of self-luminous or incoherently illuminated object distributions [1-4; see also 5-9]. As has been emphasized in previous papers, such systems are free from many of the input problems that characterize coherent spatial filtering systems and are free from the blemish noise characteristic of coherent opticalsystems in general. hybridsystems with a bipolar capability are necessary if incoherent spatial filtering is to be applied successfully to a wide range of imageprocessing problems including feature enhancement and pattern recognition. We have recently implemented an experimental system suitable for a wide range of experiments in this area. This paper reports on preliminary tests of this system. We begin with a brief analytical review of incoherent spatial filtering, then consider specific hybrid implementations for bipolar spatial filtering.

In continuation of the FRINGE Workshop Series this Proceeding contains all contributions presented at the 7. International Workshop on Advanced optical Imaging and Metrology. The FRINGE Workshop Series is dedicated to the presentation, discussion and dissemination of recent results in optical Imaging and Metrology. Topics of particular interest for the 7. Workshop are:;- New methods and tools for the generation, acquisition, processing, and evaluation of data in optical Imaging and Metrology (digital wavefront engineering, computational imaging, model-based reconstruction, compressed sensing, inverse problems solution);- Application-driven technologies in optical Imaging and Metrology (high-resolution, adaptive, active, robust, reliable, flexible, in-line, real-time);- High-dynamic range solutions in optical Imaging and Metrology (from macro to nano);- hybrid technologies in optical Imaging and Metrology;(hybrid optics, sensor and data fusion, model-based solutions,multimodality);- New optical sensors, imaging and measurement systems;(integrated, miniaturized, in-line, real-time, traceable, remote);Special emphasis is put on new strategies, taking into account the active combination of physical modeling, computer aided simulation and experimental data acquisition. In particular attention is directed towards new approaches for the extension of existing resolution limits that open the gates to wide-scale metrology, ranging from macro to nano, by considering dynamic changes and using advanced optical imaging and sensor systems.
