- Compact and robust method for full Stokes spectropolarimetryWilliam Sparks
Space Telescope Science Institute, 3700 San Martin Drive, Baltimore, Maryland 21218, USA
Appl Opt 51:5495-511. 2012..The robustness and simplicity of the approach, coupled with its potential for high sensitivity, and applicability over a wide wavelength range, is likely to prove useful for applications in challenging environments such as space...
- A search for chiral signatures on MarsWilliam B Sparks
Space Telescope Science Institute, Baltimore, MD, USA
Astrobiology 5:737-48. 2005..Our observations covered only a small fraction of parameter space, so although we obtained a null result, we cannot exclude the presence of optical activity at other wavelengths, in other locations, or at higher spatial resolution...
- Detection of circular polarization in light scattered from photosynthetic microbesWilliam B Sparks
Space Telescope Science Institute, 3700 San Martin Drive, Baltimore, MD 21218, USA
Proc Natl Acad Sci U S A 106:7816-21. 2009..We conclude that circular polarization spectroscopy could provide a powerful remote sensing technique for generic life searches...
