Publikováno v: Adaptive Optics Systems VII.

We report on a test bed to compare the performance of three different wavefront sensors, the Shack-Hartmann Wavefront Sensor (SHWFS), the Pyramid Wavefront Sensor (PWFS), and the non-linear Curvature Wavefront Sensor (nlCWFS). No single wavefront sen

Monitoring the low wind effect on the Starfire Optical Range 3.5-m telescope

Autor: Mala Mateen, Jack D. Drummond, Robert Johnson

Publikováno v: Adaptive Optics Systems VI.

The 3.5 m telescope, located in Albuquerque, New Mexico, at the Starfire Optical Range (SOR) routinely images asteroids and moons orbiting around the asteroid. However point-spread-functions (PSFs) with trefoil-like structure make it difficult to det

A direct reconstruction technique to retrieve phase in a non-linear curvature wavefront sensor

Autor: Mala Mateen, Michael D. Oliker

Publikováno v: Adaptive Optics Systems VI.

A new technique for phase retrieval in non-linear Curvature Wavefront Sensors is presented. Unlike the iterative Gerchberg-Saxton technique, this technique retrieves pupil phase in a single step. It starts by calculating the optical transfer function

A Survey of the SO J K = 1 0 –0 1 Transition toward Massive Star‐forming Regions

Autor: Peter Hofner, Esteban Araya, Mala Mateen

Publikováno v: The Astrophysical Journal Supplement Series. 167:239-255

We present the most extensive survey to date of the SO ground state transition JK = 10-01 (30 GHz). We observed 49 regions of massive star formation with the Max-Planck-Institut fur Radioastronomie (MPIfR) 100 m telescope. In addition, the SO JK = 43
