Paper Abstract

Optical systems performances can be affected by local optical turbulence created by its surrounding environment (telescope dome, clean room, atmospheric surface layer). We present recent measurements of the local turbulence inside the 1.5m M´eO telescope dome at Calern observatory (France) with the INTENSE (INdoor TurbulENce SEnsor) instrument. Relationships between the dome turbulence and the local meteorological measurements (temperature, pressure, wind speed and direction) are investigated. The impact of the local dome turbulence on the seeing at the focal plane of the 1.5 m telescope is highlighted.
