What is it about?
In this work, a fast, state-of-the-art pulsed-terahertz detection system is implemented with a unique polarization-sensitive single pixel imaging technique to recover 3D depth images of an opaque polarizing sample. With the use of pulsed (broadband) detection, hyperspectral images of the sample are obtained which leads to determination of its optical properties and chemical composition. The recovery of these polarization-resolved images also gives insight on the microscopic structure of the sample. This system has the potential to serve as a guide for future terahertz single pixel imaging systems as this technology improves and approaches adoption in a range of industries for non-destructive product inspection.
