Snapshot-Imaging Spectropolarimeter

Abstract

We have constructed a snapshot imaging spectropolarimeter for use in the visible spectrum, ultimately with the aim of obtaining imaging measurements of dynamic stress across a transparent material. After constructing the instrument, we found that a new calibration methodology was necessary in order to retain sufficient spectral resolution. Modifying the calibration enabled the instrument to obtain useful measurements, but the utility of the instrument is still severely hampered by the limitations of its design and its sensitivity to noise. This led to study of how the instrument design can be modified to optimize its performance, and how the reconstruction algorithms can be modified to improve their accuracy in the presence of noise.
