Apollo Applications Program space erectable crossed-H interferometer for long wave radio astronomy experiments and evaluation of EVA in space maintenance
Wide angle Michelson interferometer spectrometer instrument function derived by computing phase difference between beams
High resolution scanning confocal interferometer illumination requirements from quasi-paraxial ray tracing calculation, considering additional reflections effect
Michelson type interferometer for Nimbus meteorological satellite to obtain vertical temperature, humidity and ozone profile
Long wave radio astronomy interferometer system design for orbiting spacecraft, noting radio source surveys and sun and Jupiter observations
Gravitational red shift measurement using synchronous satellite, argon laser and Fabry- Perot interferometer
Fine tuning acquisition and tracking interferometer radar system uses a first antenna array of at least three receiving antennas. Array includes a reference antenna, a coarse tuning antenna, and a fine tuning antenna aligned on a receiving axis. Short range rendezvous system provides increased position accuracy.
Laser micrometer measures dimensions of precision gyro and gas bearing parts using the principle of measuring light phase changes rather than a direct fringe count. The system uses light beams to eliminate errors due to deformations and surface irregularities, and three interferometers.
Infrared interferometer spectrometer for Mariner spacecraft in Mars orbit
Michelson interferometer to detect grating table rotation in infrared spectrometer
Synthetic aperture interferometer navigation satellite concept
Laser optical simulation of spaceborne radio astronomy interferometer experiment
Short baseline radiating satellite interferometer concept for reducing satellite navigation systematic errors for aircraft and ships
Long path difference vacuum Michelson interferometer application to far IR and IR laser wavelength measurements compared with 6328 A He-Ne wavelength
Fabry-Perot interferometer with Al coating reflecting surface deposited on unbacked thin films
Standard two-beam interferometer with polarizers in each beam and an analyzer at the recombined focal point provides greater accuracy and higher resolution than any other known method for measuring variation of polarization within a spectral line and in the surrounding continuum.
Multipass holographic interferometer forms a hologram of high diffraction efficiency, and hence provides a bright and high contrast interferogram. It is used to study any effect which changes the index of refraction and to study surface deformations of a flat reflecting surface.
Fabry-Perot interferometer measurements of dielectric constants and loss for synthetic resins
