[lise] Introduction
Established on 1 January 2000 by Antoine Labeyrie, professor at the Collège de France and creator, in 1974, of the first two-telescope interferometer (I2T), the Laboratoire pour l’Interférométrie Stellaire et Exoplanétaire, known by its acronym LISE, specializes in instrumental development in the field of high-angular-resolution astronomical imaging, as well as the ultrasensitive observations made possible by these new instruments.

Originally based at the Observatoire de Haute-Provence, LISE is now hosted by the Observatoire de la Côte d’Azur (OCA). Composed of Collège de France personnel as well as associated volunteers of various backgrounds, LISE collaborates closely with the “Physical Methods for Observation” group of the Lagrange research unit at OCA.

Research is focused on
  • new optical concepts that allow increasing the strength of astronomical observations,
  • laboratory experimentation and development of prototypes that serve as precursors for larger instruments aimed at increasing both angular resolution and dynamic range,
  • astronomical observations that go beyond the existing boundaries and
  • interpretation of observational data.

 Among the astrophysical [or science] applications of the instrumentation developed by LISE are

  • exo-planets (direct observation and search for life),
  • stellar physics,
  • active galactic nuclei,
  • gamma-ray bursts and
  • gravitational lenses and cosmology.

 Some of the instrumental projects are candidates for future programs of ESO and of the ESA and NASA space agencies.
