Optical design of VIPER: a high-resolution multimode fiber-fed VIPA spectrograph for characterizing exoplanet atmospheric escape
Matthew C. H. Leung, David Charbonneau, Andrew Szentgyorgyi +1
We present the optical design of VIPER: a high-resolution, multimode fiber-fed, narrowband, cross-dispersed, seeing-limited spectrograph based on a Virtually Imaged Phased Array (V…
Crank-rocker optical fiber mode scrambler prototype for the GMT-Consortium Large Earth Finder (G-CLEF)
Matthew C. H. Leung, Colby Jurgenson, Andrew Szentgyorgyi +7
When coherent light propagates through a multimode optical fiber, the modes interfere at the fiber exit boundary, producing a high-contrast speckle interference pattern called moda…
VIPER: A high-resolution multimode fiber-fed VIPA spectrograph concept for characterizing exoplanet atmospheric escape
Matthew C. H. Leung, David Charbonneau, Andrew Szentgyorgyi +7
An increasing number of applications in exoplanetary science require spectrographs with high resolution and high throughput without the need for a broad spectral range. Examples in…
Off-axis Hartmann wavefront sensing for the GMT-Consortium Large Earth Finder (G-CLEF) red camera optics
Matthew C. H. Leung, Colby A. Jurgenson, Andrew Szentgyorgyi +10
The Hartmann test is a method used to measure the wavefront error in a focal optical system, wherein a mask with a pattern of small holes is placed at the system's aperture stop. B…
Accurately Measuring Hyperspectral Imaging Distortion in Grating Spectrographs Using a Clustering Algorithm
Matthew C. H. Leung, Shaojie Chen, Colby Jurgenson
Grating-based spectrographs suffer from smile and keystone distortion, which are problematic for hyperspectral data applications. Due to this, spectral lines will appear curved and…
Exoplanets Sciences with Nulling Interferometers and a Single-Mode Fiber-Fed Spectrograph
Ji Wang, Colby Jurgenson
Understanding the atmospheres of exoplanets is a milestone to decipher their formation history and potential habitability. High-contrast imaging and spectroscopy of exoplanets is t…
Performance Verification of the EXtreme PREcision Spectrograph
Ryan T. Blackman, Debra A. Fischer, Colby A. Jurgenson +25
The EXtreme PREcision Spectrograph (EXPRES) is a new Doppler spectrograph designed to reach a radial velocity measurement precision sufficient to detect Earth-like exoplanets orbit…
An Extreme Precision Radial Velocity Pipeline: First Radial Velocities from EXPRES
Ryan R. Petersburg, J. M. Joel Ong, Lily L. Zhao +13
The EXtreme PREcision Spectrograph (EXPRES) is an environmentally stabilized, fiber-fed, , optical spectrograph. It was recently commissioned at the 4.3-m Lowell Discove…
Enabling the next generation of scientific discoveries by embracing photonic technologies
Nemanja Jovanovic, Charles Beichman, Cullen Blake +46
