Abstract
Our objective is the development of mid-infrared imaging at the VLTI.
The related science case study demonstrates the enormous capability of
a new generation mid-infrared beam combiner. MATISSE will constitute an
evolution of the two-beam interferometric instrument MIDI by increasing
the number of recombined beams up to four. MIDI is a very successful
instrument which offers a perfect combination of spectral and angular
resolution. New characteristics present in MATISSE will give access to
the mapping and the distribution of the material (typically dust) in
the circumstellar environments by using a wide mid-infrared band
coverage extended to L, M, N and Q spectral bands. The four beam
combination of MATISSE provides an efficient UV-coverage: 6 visibility
points are measured in one set and 4 closure phase relations which can
provide for the first time aperture synthesis images in the
mid-infrared spectral regime. The mid-infrared spectral domain is very
relevant for the study of the environment of various astrophysical
sources. Our science case studies show the wide field of applications
of MATISSE. They will be illustrated in the first part of this
presentation through the perspective of imaging the circumstellar
environments/discs of young stellar objects. The MATISSE
characteristics will be given in a second part of the presentation.
