Infrared Michelson Interferometry of Zeta Aurigae Type Supergiants

Infrared Studies of Epsilon Aurigae in Eclipse

We report here on a series of medium resolution spectro-photometric observations of the enigmatic long period eclipsing binary epsilon Aurigae, during its eclipse interval 20092011, using near-infrared spectra obtained with SpeX on IRTF, mid-infrared spectra obtained with BASS on AOES and IRTF, MIRSI on IRTF and MIRAC4 on MMT, along with mid-infrared photometry using MIRSI on IRTF and MIRAC4 on...

Michelson Interferometry with the Keck I Telescope

We report the Ðrst use of Michelson interferometry on the Keck I telescope for di†ractionlimited imaging in the near-infrared JHKL bands. By using an aperture mask located close to the f/25 secondary, the 10 m Keck primary mirror was transformed into a separate-element, multiple-aperture interferometer. This has allowed di†raction-limited imaging of a large number of bright astrophysical target...

Adaptive Optics for Michelson Interferometry DIPLOMARBEIT

Precise distance measurement is crucial for the high-precision industry as the semiconductor manufacturing is one. Measurement devices based on the concept of a Michelson interferometer are widely used to implement a very accurate and non-contact distance measurement with nanometer resolution. Interferometers are often applied in environments where the optical path is uncovered and influenceabl...

Fourier Transforms By White-Light Interferometry: Michelson Stellar Interferometer Fringes

The white-light compensated rotational shear interferometer (coherence interferometer) was developed in an effort to study the spatial frequency content of passively illuminated white-light scenes in real-time and to image sources of astronomical interest at high spatial frequencies through atmospheric turbulence. This work was inspired by Professor Goodman’s studies of the image formation prop...
