Abstract

A variety of industrial processes would be enhanced by using appropriate imaging systems, capable of precise monitoring of the spatial distribution of species that are responsible for the underlying process (chemical reactions, multi-phase flows, etc.) Such systems can be an important step in building a closed-loop feedback system for automated control. The image refresh rate is a critical parameter for applications where timing is crucial, hence the necessity to develop optical and other tomographic techniques that allow a high sampling frequency. Furthermore, for a field-deployable optical tomographic system, an all-optoelectronic solution (AOES) is desirable for portability, compactness, light weight, low power consumption and low-maintenance. An AOES can offer application-specific spectral selectivity, thus enabling tomography of a particular chemical species.
