Quasi-optical Mm-wave sensor system for contactless monitoring of small samples with enhanced performance

摘要

Millimeter wave sensing systems suffer from measurement inaccuracies when the waist of the radiated beam is relatively larger than the size of the test targets. In order to mitigate the issue, we designed a quasi-optical lens system, which enhances the dynamic range and sensitivity of the millimeter wave sensor system, compared with lens-less sensor systems.
