摘要：
The concept of using adaptive optics based deformable mirror for near field microwave imaging of penetrable objects is presented in this paper. The deformable mirror microwave tomography technique proposed for inverse scattering applications relies on the use of an adaptive mirror to steer the electromagnetic ( EM) field for multi-view irradiation of an unknown dielectric object using a fixed EM source. The deformable mirror tomography method offers higher degrees of freedom in that a large number of field measurements can be recorded by adaptively changing the mirror shape during data acquisition. In this paper, the potential of a deformable mirror to yield useful field measurements for reliable permittivity reconstruction is investigated via computer simulations for TMz polarization. The investigation also includes the robustness of the novel imaging technique in recovering the unknown permittivity distribution in the presence of noise.
