Abstract: New generation of radio interferometers are envisaged to produce high quality, high dynamic range Stokes images of the observed sky from the corresponding under-sampled Fourier domain measurements. In practice, these measurements are contaminated by the…

Abstract: Polarization manipulation plays an important role in real applications. In this article, full polarization transformation using graphene has been first achieved in microwave frequencies. Without the aid of lumped elements like varactors or p-i-n diodes…

Abstract: The hyperspectral full polarization imaging system (HFPIS) based on spatial modulation and liquid crystal tunable filter (LCTF) can modulate the polarization information of the target into the interferogram by means of interference imaging. It has…

Abstract: We propose a method for measuring the full polarization states of a light field by using hybrid polarization-angular multiplexing digital holography based on geometric phase. Through acquiring the geometric phase distribution of the whole light…
