Enabling efficient injection of light into single-mode fibers (SMFs) is a key requirement in realizing diffraction-limited astronomical spectroscopy on ground-based telescopes. SMF-fed spectrographs, facilitated by the use of adaptive optics (AO), of

Methods and results are described for flight-test measurements of the aero-optical effect of the near-field flow surrounding a medium-sized helicopter in hover. The data were acquired using a novel, passive measurement approach in which optical wave-

We are developing a stable and precise spectrograph for the Large Binocular Telescope (LBT) named "iLocater." The instrument comprises three principal components: a cross-dispersed echelle spectrograph that operates in the YJ-bands (0.97-1.30 microns

The current generation of precision radial velocity (RV) spectrographs are seeing-limited instruments. In order to achieve high spectral resolution on 8m class telescopes, these spectrographs require large optics and in turn, large instrument volumes

This paper gives a background into aero-optics which is the effect that turbulent flow over and around an aircraft has on a laser projected or received by an optical system. The background also discusses the magnitude of the detrimental effects that

A feedforward adaptive-optic correction approach was investigated in which the return light from an artificial guide star is used to synchronize the deformable mirror with the regularized aberrations of a forced compressible shear layer with high- an

The aero-optic aberrations due to a compressible shear-layer flow with high- and lowspeed Mach numbers of 0.75 and 0.12 were measured using the return light from an artificial guide star. The guide star was created by focusing a pulsed, frequency-tri

Use of an airborne platform for a directed energy system is currently severely limited by aero-optic aberrations arising from density variations in air flowing over the aircraft; the primary limitation is for aft pointing applications. Innovative Tec
