Abstract :
Recent progress in millimeter-wavelength optics, antennas, receivers and other components permits greatly enhanced system performance in a wide range of applications. Arrays of detectors in the focal plane offer a major avenue for increasing the data rate of millimeter-wave imaging systems. All-reflective systems with focal-plane arrays of monolithic elements promise major improvements in millimeter-wave imaging applications. In this review we discuss some of the general characteristics of millimeter-wave focal plane imaging systems and associated optics using a single paraboloidal reflector. The evaluation of coupling and aperture efficiency is presented at the same time
