Research

I direct the Laboratory for Engineering Non-traditional Sensors (LENS). As the name suggests, the primary research activity is the invention, design, construction, and testing of novel optical sensor systems. Our efforts can best be described as computational sensing—an approach that performs certain sensor processing optically (prior to electronic sampling) rather than via standard post-processing of the sampled data. Doing so results in sensor systems with revolutionary performance and physical characteristics.

Recently, we have started a second research thrust into the rapid fabrication of volumetric terahertz optical components. Our lab is equipped with a rapid-prototyping machine (i.e. 3-D printer), and it can be used to easily fabricate complicated optical components that are either impossible or extremely expensive via traditional methods. We are investigating how this technology can be modified and expanded to increase the range of possible components.
