Guest Editorial: Overview of the Special Issue and a Dialog on Starshades
Jonathan Arenberg, Anthony Harness, Rebecca Jensen-Clem
This special issue is dedicated to starshades: science, engineering, technology and programmatics. Our reasons for organizing this special issue are several fold. First as a new te…
Exoplanet Detection in Starshade Images
Mengya, Hu, Anthony Harness +2
A starshade suppresses starlight by a factor of 1E11 in the image plane of a telescope, which is crucial for directly imaging Earth-like exoplanets. The state of the art in high co…
Optical Verification Experiments of Sub-scale Starshades
Anthony Harness, Stuart Shaklan, Phillip Willems +7
Starshades are a leading technology to enable the detection and spectroscopic characterization of Earth-like exoplanets. In this paper we report on optical experiments of sub-scale…
Implementing non-scalar diffraction in Fourier optics via the Braunbek method
Anthony Harness
Fourier optics is a powerful and efficient tool for solving many diffraction problems, but relies on the assumption of scalar diffraction theory and ignores the three-dimensional s…
Bernoulli generalized likelihood ratio test for signal detection from photon counting images
Mengya Hu, He Sun, Anthony Harness +1
Because exoplanets are extremely dim, an Electron Multiplying Charged Coupled Device (EMCCD) operating in photon counting (PC) mode is necessary to reduce the detector noise level…
