Target entity: intensity interferometer
Context triple: [Robert Hanbury Brown, coInventorOf, intensity interferometer]
  • A. Michelson interferometer
    The Michelson interferometer is a precision optical instrument that splits and recombines light beams to measure extremely small differences in path length, widely used in fundamental physics experiments and metrology.
  • B. Very Long Baseline Interferometry
    Very Long Baseline Interferometry is a radio astronomy technique that combines signals from widely separated antennas to achieve extremely high angular resolution and precisely measure geodetic and astronomical parameters.
  • C. Very Long Baseline Array
    The Very Long Baseline Array is a continent-spanning network of ten radio telescopes used for high-resolution astronomical observations through very long baseline interferometry.
  • D. 20 Meter Telescope
    The 20 Meter Telescope is a mid-sized radio telescope at the Green Bank Observatory used for astronomical research and education in radio astronomy.
  • E. Imaging IR Spectrometer
    The Imaging IR Spectrometer is a Chandrayaan-2 orbiter instrument designed to map the Moon’s surface composition by measuring reflected and emitted infrared radiation.
  • F. None of above. chosen
