On-sky results for the novel integrated micro-lens ring tip-tilt sensor
Philipp Hottinger, Robert J. Harris, Jonathan Crass +16
We present the first on-sky results of the micro-lens ring tip-tilt (MLR-TT) sensor. This sensor utilizes a 3D printed micro-lens ring feeding six multi-mode fibers to sense misali…
3D-M3: High-spatial resolution spectroscopy with extreme AO and 3D printed micro-lenslets
Theodoros Anagnos, Mareike Trappen, Blaise C. Kuo Tiong +20
By combining IFS with ExAO we are now able to resolve objects close to the diffraction-limit of large telescopes, exploring new science cases. We introduce an IFU designed to coupl…
An innovative integral field unit upgrade with 3D-printed micro-lenses for the RHEA at Subaru
Theodoros Anagnos, Pascal Maier, Philipp Hottinger +26
In the new era of Extremely Large Telescopes (ELTs) currently under construction, challenging requirements drive spectrograph designs towards techniques that efficiently use a faci…
Diffraction-limited integral-field spectroscopy for extreme adaptive optics systems with the Multi-Core fiber-fed Integral-Field Unit
Sebastiaan Y. Haffert, Robert J. Harris, Alessio Zanutta +31
Direct imaging instruments have the spatial resolution to resolve exoplanets from their host star. This enables direct characterization of the exoplanets atmosphere, but most direc…
Demonstration of a photonic lantern low order wavefront sensor using an adaptive optics testbed
Mark K. Corrigan, Timothy J. Morris, Robert J. Harris +1
We demonstrate the use of an optimized 5 core photonic lantern (PL) to simultaneously measure tip/tilt errors at the telescope focal plane, while also providing the input to an ins…
Optimizing astrophotonic spatial reformatters using simulated on-sky performance
Theodoros Anagnos, Robert J. Harris, Mark K. Corrigan +7
One of the most useful techniques in astronomical instrumentation is image slicing. It enables a spectrograph to have a more compact angular slit, whilst retaining throughput and i…
NAIR: Novel Astronomical Instrumentation through photonic Reformatting
Robert J. Harris, Jan Tepper, John J. Davenport +11
The project "Novel Astronomical Instrumentation through photonic Reformatting" is a DFG-funded collaboration to exploit the recognized potential of photonics solutions for a radica…
Simulation and Optimization of an Astrophotonic Reformatter
Th. Anagnos, R. J. Harris, M. K. Corrigan +7
Image slicing is a powerful technique in astronomy. It allows the instrument designer to reduce the slit width of the spectrograph, increasing spectral resolving power whilst retai…
