Abstract
In this article we present the concept of APreS-MIDI (APerture Synthesis in the MID-Infrared). This optical extension for the already very successful operating MIDI instruments will allow for the combination of up to four telescope beams. With APreS-MIDI high resolution imaging by aperture synthesis will be possible for the first time in the mid-infrared spectral regime. The optical setup uses a special principle for beam combination, where interference fringes are sampled in the pupil plane. This principle can also be suitable for future interferometers.
