24. The Ingot Wavefront Sensor: general updates and lab activities

Talk

The Ingot Wavefront Sensor represents a new class of sensors that are aimed to overcome the limitations imposed by the LGSs geometry, which differently from NGSs, are not point-like sources but more elongated objects in the sky. The current design uses a reflective roof-shaped prism to split the light into three pupils that are used to retrieve the wavefront shape. In this work, we present the...

11. MFBD and IFT data modeling for high-resolution high-contrast imaging

Talk

In the context of high-contrast imaging of exoplanets in the visible band through extreme adaptive optics, the forthcoming SHARK-VIS imager for the LBT implements the concept of high-cadence imaging at millisecond frame rate, thanks to a low noise sCMOS camera that freezes the evolution of the AO residual speckles. This allows the simultaneous exploitation of both spatial and temporal...

25. Integral Field Units (IFU) for AO focal plane: the case study of ELVIS, the new IFU for SHARK-VIS

Giorgio Viavattene (INAF - Osservatorio Astronomico di Roma)

Talk

ELVIS (Exoplanets at LBT with a Visible IFS for Shark-vis) is an add-on Integral Field Unit (IFU) to be integrated in the new LBT high-contrast high-resolution AO-assisted imager SHARK-VIS. The spectrograph, which provides a spectral resolution of 10-20k at H-alpha is fed by fiber bundles with at least 12x12 spaxels. This configuration, thanks to an optimized VPH dispersing element designed...

27. Innovative VPH gratings for ELVIS (Exoplanet LBT Visible Imaging Spectrograph)

Michele Frangiamore (Istituto Nazionale di Astrofisica (INAF))

Talk

The Exoplanet LBT Visible Imaging Spectrograph (ELVIS) embedded into the high contrast and resolution AO-assisted imager SHARK-VIS at Large Binocular Telescope 2 x 8.4m (LBT) is an upgrade of existing Integral Field Unit (IFU) to permit e newer comprehension of young accreting substellar and planetary companions with higher contrast (up to 10-5) in their H-alpha emission with respect to...
