A Terahertz Superconducting Single-Pixel Imaging System Using DMD

We propose a terahertz superconducting single-pixel imaging system with a single hot electron bolometer (HEB) detector combined with a digital-mirror-device (DMD). With the DMD as a programmed coding reflector, the proposed imaging system could acquire coded measurement results of an imaged scene rapidly even with a single detector. Base on compressive sensing (CS) techniques, the imaged scene was reconstructed by fewer coded measurements compared to the image size. We demonstrated that the proposed single-pixel imaging system framework could significantly improve the imaging efficiency and resolution.
