| Popis: | International audience; In this paper, we present a new concept of instrument for high resolution imaging in astronomy, involvingthe sum frequency generation in non-linear waveguides. The aim is to convert the infrared radiationemitted by an astronomical source to the visible spectral domain where the optical components aremature and efficient. We present the main experimental results obtained in laboratory, and propose a newdesign for this instrument for its implementation on the Center for High Angular Resolution Astronomy(CHARA) telescope array. Preliminary stability and photometric results obtained at CHARA are pre-sented. Using these last measurements, we estimate the limiting magnitudes which could be reached bythis interferometer in the H spectral band. |
