Observation of a short-lived pattern in the solar chromosphere [PDF]

open access: yes, 2006
In this work we investigate the dynamic behavior of inter-network regions of the solar chromosphere. We observed the chromosphere of the quiet Sun using a narrow-band Lyot filter centered at the Ca II K 2v emission peak with a bandpass of 0.3A.

Constraints on the Galactic bar from the Hercules stream as traced with RAVE across the Galaxy [PDF]

open access: yes, 2014
Non-axisymmetries in the Galactic potential (spiral arms and bar) induce kinematic groups such as the Hercules stream. Assuming that Hercules is caused by the effects of the outer Lindblad resonance of the Galactic bar, we model analytically its ...

Mode-shape measurement of piezoelectric plate using temporal speckle pattern interferometry and temporal standard deviation

open access: yesOptics Letters, 2011
This study proposes an image processing method to improve the quality of interference fringes in mode-shape measurement using temporal speckle pattern interferometry. A vibrating piezoelectric plate at resonance was investigated, and the full-field optical information was saved as a sequence of images.
