Resolution limits of pixellated optical components (2016)
Presentation / Conference Contribution
Cowie, E. N., Bourgenot, C., Robertson, D., & Courtial, J. (2016). Resolution limits of pixellated optical components. In A. J. Davis, C. F. Hahlweg, & J. R. Mulley (Eds.), Novel optical systems design and optimization XIX. https://doi.org/10.1117/12.2237826

Pixellated optical components, for example generalised confocal lenslet arrays (GCLAs), enable the design of optical devices which cannot be realised without introducing pixellation or a similar compromise. A key concern is the degradation of imaging... Read More about Resolution limits of pixellated optical components.

Adaptive optics for wide-field microscopy (2011)
Presentation / Conference Contribution
Bourgenot, C., Saunter, C., Girkin, J., & Love, G. (2011). Adaptive optics for wide-field microscopy. . https://doi.org/10.1117/12.873857

We report on recent developments in the use of adaptive optics (AO) in wide-field microscopy to remove both system and sample induced aberrations. We describe progress on using both a full AO system and image optimization techniques (wavefront sensor... Read More about Adaptive optics for wide-field microscopy.

Design, manufacture, and evaluation of prototype telescope windows for use in low-vision aids (2017)
Presentation / Conference Contribution
Young, L., Robertson, D., Love, G., Girkin, J., Cowie, E., Bourgenot, C., & Courtial, J. (2017). Design, manufacture, and evaluation of prototype telescope windows for use in low-vision aids. In A. J. Davis, C. F. Hahlweg, & J. R. Mulley (Eds.), Novel optical systems design and optimization XX. https://doi.org/10.1117/12.2272992

Pixellated Optics, a class of optical devices which preserve phase front continuity only over small sub areas of the device, allow for a range of uses that would not otherwise be possible. One potential use is as Low Vision Aids (LVAs), where they ar... Read More about Design, manufacture, and evaluation of prototype telescope windows for use in low-vision aids.

Marchetti, L. M. Close, & J. Véran (Eds.), Adaptive Optics Systems V (990948-990948-7). https://doi.org/10.1117/12.2231721

CHOUGH is a small, fast project to provide an experimental on-sky high-order SCAO capability to the 4.2m WHT telescope. The basic goal has r0-sized sub- apertures with the aim of achieving high-Strehl ratios (> 0:5) in the visible (> 650 nm). It achi...

BigBOSS will include 5,000... Read More about Optical fiber systems for the BigBOSS instrument.

Studying focal ratio degradation of optical fibers for Subaru's Prime Focus Spectrograph. (2014)
Presentation / Conference Contribution
dos Santos, J., de Oliveira, A., Gunn, J., de Oliveira, L., Vital de Arruda, M., Castilho, B., …de Oliveira, C. (2014). Studying focal ratio degradation of optical fibers for Subaru's Prime Focus Spectrograph. In R. Navarro, C. R. Cunningham, & A. A. Barto (Eds.), Advances in Optical and Mechanical Technologies for Telescopes and Instrumentation. https://doi.org/10.1117/12.2056460

Focal Ration Degradation (FRD) is a change in light’s angular distribution caused by fiber optics. FRD is important to fiber-fed, spectroscopic astronomical systems because it can cause loss of signal, degradation in spectral resolution, or increased...
