Abstract
We are studying an optical concept aiming at recombining four
mid-infrared telescope beams, where interference fringes are sampled in
the pupil plane. Such a principle is perfectly adapted for
reconstructing images by aperture synthesis with teh VLTI. It could be
used for building a new generation 10 μm instrument, but instead of
doing a totally new instrument, we propose the design of an optical
module that can supply the surrent MIDI-VLTI instrument with 4 beams.
The combined use of this module together with the MIDI instrument is
the
project called APreS-MIDI. Such an instrument at the VLTI focus will
have an unique and very strong astrophysical potential.
