【 摘 要 】
We present the instrument and first results of a Low Layer SCIDAR (Scintillation Detection and Ranging), called new generation LOLAS (LOLAS 2), which consists of the optical coupling of a Ritchey-Chrétien telescope and an EMCCD camera, and allows the measurements of optical turbulence profiles in the atmosphere from ground level with high altitude-resolution. The system is designed for widely separated double star targets, which enables a high altitude resolution of 5 ≤ Δh ≤ 35 meters above the first kilometer , measured from ground level. The first results were obtained in June and November 2013, and May 2014 at the Observatorio Astronomico Nacional de San Pedro Mártir (OAN-SPM), México.
