Analogous to an optical single-pixel camera, we are developing a monostatic scanning holographic imaging scheme in microwave/mmWave frequencies to visualize the permittivity distribution of dielectric materials. In order to dramatically decrease the sample rate for successful reconstruction, Compressed Sensing (CS) and regularization techniques are utilized in our system architecture. Rapid microwave imaging can be applied in cancer cell detection, nondestructive testing (NDT), weapon detection and much more.

Microwave imaging attracts lots of attention in these years for non-invasive measurement and less harmful to humans. In my research, the distorted Born iterative method (DBIM) is applied to measure the permittivity of the material in the free space. Besides, Multilevel Green's Function Interpolation Method (MLGFIM) is also considered to lower the computational complexity and improve the imaging quality.
