Abstract
Free-atmosphere, and surface-layer optical-turbulence have been extensively monitored over the years. The optical-turbulence inside a telescope enclosure en the other hand has yet to be as fully characterized. For this latest purpose, an experimental concept, LOTUCE (LOcal TUrbulenCe Experiment) has been developed in order to measure and characterise the so-called dome-seeing. LOTUCE2 is an upgraded prototype whose main aim is to measure optical turbulence characteristics more precisely by minimising cross-contamination of signals. This characterisation is both quantitative (optical turbulence strength) and qualitative (assessing the optical turbulence statistical model). We present the new opto-mechanical design, with the theoretical capabilities and limitations to the actual models.
