The anisoplanatic point-spread function in adaptive optics [PDF]
, 2006 The effects of anisoplanatism on the adaptive optics point‐spread function are investigated. A model is derived that combines observations of the guide star with an analytic formulation of anisoplanatism in order to generate predictions for the adaptive ...

Photometry using the Infrared Array Camera on the Spitzer Space Telescope [PDF]
, 2008 We present several corrections for point-source photometry to be applied to data from the Infrared Array Camera (IRAC) on the Spitzer Space Telescope. These corrections are necessary because of characteristics of the IRAC arrays and optics and the way ...

An Improved Technique for the Photometry and Astrometry of Faint Companions
, 2009 We propose a new approach to differential astrometry and photometry of faint companions in adaptive optics images. It is based on a prewhitening matched filter, also referred to in the literature as the Hotelling observer.

Wavefront Correction and Photometry for Supernova Observations
The study and identification of Supernovas rely heavily on the implementation of adaptive optics and photometry. Research on this specific astrological event is extremely significant in advancing discoveries in the realm of the life cycle of stars and ...

Final Report: Deconvolution of Adaptive Optics Images of Titan, Neptune, and Uranus
, 2002 This project involved images of Titan, Neptune, and Uranus obtained using the 10-meter W.M. Keck II Telescope and its adaptive optics system. An adaptive optics system corrects for turbulence in the Earth's atmosphere by sampling the wavefront and ...

Deep and accurate near-infrared photometry of the Galactic globular cluster omega Cen
, 2009 We present deep and accurate Near-Infrared (NIR) photometry of the Galactic Globular Cluster omega Cen . Data were collected using the Multi-Conjugate Adaptive Optics Demonstrator (MAD) mounted on the VLT (ESO).

Surface reflection model estimation from naturally illuminated image sequences [PDF]
, 1997 This thesis addresses the problem of estimating the surface reflection model of objects observed in a terrestrial scene, illuminated by natural illumination; that is, a scene which is illuminated by sun and sky light alone.
