Integrated detector arrays for high resolution far-infrared imaging


Neikirk, Dean Paul (1984) Integrated detector arrays for high resolution far-infrared imaging. Dissertation (Ph.D.), California Institute of Technology.


Imaging systems designed to operate in the millimeter and submillimeter portion of the spectrum (often referred to as the far-infrared) require the development of focal plane detector arrays to simplify their construction. In this study the general characteristics of an antenna array intended to provide diffraction limited imaging are discussed. Two line-imaging bow-tie antenna arrays utilizing the hyperhemispherical substrate lens optical system and operating at 1.22mm and 119µm, are demonstrated. Two new far-infrared detectors, the bismuth air-bridge microbolometer and the bismuth-antimony microthermocouple, have been used with these arrays. Thermal models and performance data for these detectors are given. Finally, the photolithographic processes used to fabricate the detectors and antennas are discussed.
