Speckle Interferometry at Soar in 2014
The results of speckle interferometric observations at the Southern Astrophysical Research Telescope (SOAR) telescope in 2014 are given. A total of 1641 observations were taken, yielding 1636 measurements of 1218 resolved binary and multiple stars and 577 non-resolutions of 441 targets. We resolved for the first time 56 pairs, including some nearby astrometric or spectroscopic binaries and ten ...
متن کاملSpeckle interferometry at the Blanco and SOAR telescopes
The results of speckle interferometric measurements of binary and multiple stars conducted in 2008 and 2009 at the Blanco and SOAR 4-m telescopes in Chile are presented. A total of 1898 measurements of 1189 resolved pairs or sub-systems and 394 observations of 285 unresolved targets are listed. We resolved for the first time 48 new pairs, 21 of which are new sub-systems in close visual multiple...
متن کاملNew methods for masked-aperture and speckle interferometry
Diffraction-limited images can be obtained with a large optical telescope using interferometry. One such method for objects of sufficient brightness is non-redundant masking (NRM), in which observations are made through a pupil mask that contains an array of small holes. However, NRM only uses a small fraction of the available light. Here I describe a method for Extended NRM in which a cylindri...
متن کاملOn the Phase Unwrapping of Speckle Interferometry Maps
This paper aims to provide an effective and distortion-free approach for the phase unwrapping of digital speckle pattern interferometry (DSPI) maps. DSPI is a very powerful measurement tool among industrial users. However, high percentages of noise are present in the experimental data obtained from the method and, therefore, most phase unwrapping algorithms fail to restore the correct phase fil...
متن کاملTime-resolved measurements from speckle interferometry.
We present time-resolved measurements by speckle interferometry of the light scattered by a liquid medium. Measurements were performed by use of reflectance geometry and are compared with results obtained in the same conditions with a femtosecond laser and a streak camera. The setup was also tested in vivo on the forearm of a human volunteer to demonstrate the potential utility of such a setup ...
