Achieving high contrasts with slicer based integral field spectrographs

Abstract:

We demonstrate experimentally that slicer based integral field spectrographs are an attractive choice for the next generation of exoplanet direct detection instruments. By propagating a single simulated speckle though a slicer based integral field spectrograph (IFS) and performing the post processing technique of spectral deconvolution we are able to achieve a speckle rejection factor of ∼600 in broadband images (and ∼100 in individual wavelength channels) with contrasts only appearing to be ...
