Speckle interferometry observations with the 3.67 m Advanced Electro Optical System Telescope at the Haleakala Observatory failed to detect a secondary component.

Star A was first resolved into three components using speckle interferometry, although they can now be directly imaged using space-based or adaptive optics.

Using speckle interferometry, McAlister ( 1982 ) obtained mass estimates of for the primary and for the secondary, where is the mass of the Sun.

A search for a faint companion using the Hubble Space Telescope Wide Field Planetary Camera revealed nothing, nor did a search with near-infrared speckle interferometry.

One more recent type of speckle interferometry called speckle masking involves calculation of the " aperture masking technique was pioneered by the Cavendish Astrophysics Group.

A fifth component of this system, orbiting one of the ? 2 pair, was detected by speckle interferometry in 1985 and confirmed in two subsequent observations.

During 2000, speckle interferometry measurements from the Telescopio Nazionale Galileo in the Canary Islands were used to measure the apparent size and shape of 30 Urania.

For many years telescope performance was limited by this effect, until the introduction of speckle interferometry and adaptive optics provided a means of removing this limitation.

Radar and speckle interferometry observations show that the shape of Victoria is elongated, and it is suspected to be a binary asteroid, with a moon of irregular shape.

Using the speckle interferometry technique, R136a was shown to be made up of 8 stars within 1 arcsecond at the centre of the cluster, with R136a1 being the brightest.
