We present results from imaging polarimetry (IP) of upper solar atmospheres during a total solar eclipse on 2012 November 13 and spectropolarimetry of an annular solar eclipse on 2010 January 15. This combination of techniques provides both the synop... Read More about On the Combination of Imaging-polarimetry with Spectropolarimetry of Upper Solar Atmospheres during Solar Eclipses.

Modelling complex phenomena in optical fibres (2012)
Presentation / Conference Contribution
Allington-Smith, J., Murray, G., & Lemke, U. (2012, December). Modelling complex phenomena in optical fibres. Presented at Ground-based and Airborne Instrumentation for Astronomy IV, Amsterdam

We present a new model for predicting the performance of fibre systems in the multimode limit. This is based on ray-­‐tracing but includes a semi-­‐empirical description of Focal Ratio Degradation (FRD). We show how FRD is simulated by the model. Wit...

We describe the fiber optics systems for use in BigBOSS, a proposed massively parallel multi-object spectrograph for the Kitt Peak Mayall 4-m telescope that will measure baryon acoustic oscillations to explore dark energy. BigBOSS will include 5,000... Read More about Optical fiber systems for the BigBOSS instrument.

Optical design of optical switches for diverse field spectroscopy (2010)
Presentation / Conference Contribution
Content, R., Murray, G. J., & Allington-Smith, J. R. (2010, December). Optical design of optical switches for diverse field spectroscopy. Presented at Modern Technologies in Space- and Ground-based Telescopes and Instrumentation, San Diego, California

Diverse field spectroscopy is a new concept in which any part of a field can be optically captured and send to the entrance slit of a spectrograph. It is more general than integral field spectroscopy, multi-object spectroscopy and even multi-integral... Read More about Optical design of optical switches for diverse field spectroscopy.

Characterising modal noise in fibre-coupled spectrographs for astronomy (2010)
Presentation / Conference Contribution
Lemke, U., Corbett, J., Allington-Smith, J., & Murray, G. (2010, December). Characterising modal noise in fibre-coupled spectrographs for astronomy. Presented at Conference on Modern Technologies in Space- and Ground-Based Telescopes and Instrumentation, San Diego, CA

Fibre modal noise occurs in high spectral resolution, high signal-to-noise applications. It imposes fundamental limits upon the photometric accuracy of state-of-the-art fibre-spectrograph systems. In order to maximize the performance of current and f... Read More about Characterising modal noise in fibre-coupled spectrographs for astronomy.
