Dual Band Kinetic Inductance Bolometers for Submillimeter-wave Imaging: Experimental and Theoretical Optical Response

In this contribution, a focal plane array (FPA) at submillimeter wavelengths is presented for security applications. The detectors are based on kinetic inductance bolometers. Two frequency selective absorber (FSA) sets were designed to implement a security imager. The effective pattern of the imager coupled to a black body point source over a...

Analysis of Absorber Based Imaging Systems with Distributed Incoherent Sources

Passive imaging cameras at sub-millimeter wave-lengths are currently entering a new era with the development of large format arrays of direct detectors. Several of these arrays are being developed with bare absorbing meshes without any antenna coupling (lens or horn) structures. This paper uses a spectral electromagnetic model to analyze the...
