Fast photon counting detectors with 1 ns time resolution and NEP less than 10(exp -17) W/square root of Hz can resolve all photon arrivals from bright far-infrared sources cataloged by AKARI. Intensity correlation due to photon bunches enable delay time measurements, and complex visibility is obtained for aperture synthesis imaging. Precise timing measurements on independent cryogenic telescopes and formation flights enable a long baseline intensity interferometer in space. In this paper, we discuss on a simulation based study to compare the intensity interferometry with heterodyne (amplitude) interferometry. Although the intensity interferometry requires longer integration time for the delay time measurements, the intensity cross correlation is stable against atmospheric phase fluctuation, which enables long baseline observations from ground. From space, sensitivity gain of direct detectors and photon counting detectors over heterodyne technologies can be several orders of magnitude under low background condition. The THz intensity interferometers can resolve many compact AKARI sources with angular resolution better than ALMA, and resolve inner region of protoplanetary disks and active galactic nuclei.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態:
