Long-term performance of the MLR-TT sensor: two-photon polymerization validation in the telescope environment
Robert J. Harris, Philipp Hottinger, Jonathan Crass +2
We report on the long-term optical performance of a two-photon polmerized microlens ring tip-tilt sensor. The study is backed by repeated measurements over the last six years, sinc…
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…
Focal Plane Tip-Tilt Sensing for Improved Single-Mode Fiber Coupling using a 3D-printed Microlens-Ring
Philipp Hottinger, Robert J. Harris, Philipp-Immanuel Dietrich +11
Modern extreme adaptive optics (AO) systems achieving diffraction-limited performance open up new possibilities for instrumentation. Especially important for the fields of spectros…
Micro-lens array as tip-tilt sensor for single-mode fiber coupling
Philipp Hottinger, Robert J. Harris, Philipp-Immanuel Dietrich +8
We introduce a design for a tip-tilt sensor with integrated single-mode fiber coupling for use with the front-end prototype of the iLocater spectrograph at the Large Binocular Tele…
