The main objective of this activity is to develop new focal plane coupling array concepts and technologies that optimise the coupling from reflector optics to the large number of detectors for next generation sub millimetre wave telescopes particularly targeting measurement of the polarization of the cosmic microwave background (CMB). In this 18 month TRP programme the consortium are tasked wit...
A technique for the real time reduction of the astrometric position of a moving object detected against a background of reference stars has been developed for satellite and asteroid measurements. The technique has been implemented for the Lincoln Near Earth Asteroid Research (LINEAR) system and is currently being adapted for the space surveillance application and installed in the Moron Optical ...
James E. Harvey Martina Atanassova Andrey Krywonos University of Central Florida Center for Research and Education in Optics and Lasers CREOL P.O. Box 162700 4000 Central Florida Boulevard Orlando, Florida 32826 Abstract. Most imaging systems today include a mosaic detector array in the focal plane. Optical designers of astronomical telescopes typically produce a design that yields a superb on-...
Wavefronts can be accurately estimated directly from either focal plane images or defocused pupil plane images, in schemes similar to phase diversity. These wavefront sensing techniques offers fundamental advantages over more traditional techniques for high contrast Adaptive Optics. When combined with a high performance coronagraph, these techniques enable efficient detection of exoplanets. 1. ...
Using the method developed by Hardebeck and Shearer (2002, 2003) termed the HASH method, we calculate focal mechanisms for earthquakes that occurred in the southern California region from 1981 to 2010. When available, we use hypocenters refined with differential travel times from waveform cross correlation. Using both the P-wave first motion polarities and the S/P amplitude ratios computed from...
