Experimental and on-sky demonstration of spectrally dispersed wavefront sensing using a photonic lantern
Jonathan Lin, Michael P. Fitzgerald, Yinzi Xin +12
Adaptive optics systems are critical in any application where highly resolved imaging or beam control must be performed through a dynamic medium. Such applications include astronom…

Spectral characterization of a 3-port photonic lantern for application to spectroastrometry
Yoo Jung Kim, Michael P. Fitzgerald, Jonathan Lin +10
Spectroastrometry, which measures wavelength-dependent shifts in the center of light, is well-suited for studying objects whose morphology changes with wavelength at very high angu…

On the Potential of Spectroastrometry with Photonic Lanterns
Yoo Jung Kim, Michael P. Fitzgerald, Jonathan Lin +5
We investigate the potential of photonic lantern (PL) fiber fed spectrometers for two-dimensional spectroastrometry. Spectroastrometry, a technique for studying small angular scale…
