TL;DR: In this paper, the authors describe test and analysis methods for optical performance verification of the Integrated Science Instrument Module (ISIM) with an emphasis on the processes used to plan and execute the test.
Speckle differential imagery performance using a JWST tunable filter etalon prototype
TL;DR: In this article, a low-order Fabry-Perot etalon was used for speckle suppression in multi-wavelength imaging, a technique widely used by existent and future ground-based high contrast imaging capabilities.
