Diffraction-limited imaging at IR wavelengths using aperture masks and fully-filled apertures

چکیده
The performance of a phase recovery algorithm developed for speckle data collected using a pupil-plane mask has been investigated for use at near infrared wavelengths. The method, based on the radio-astronomical self-calibration technique, has been tested alongside a state-of-the-art implementation of the Knox-Thompson scheme using both simulated and real specklegrams. Our results indicate that the new procedure is as effective as the Knox-Thompson based image reconstruction scheme and is applicable to a wide range of astrophysically interesting sources.

The recent successes in diffraction limited optical imaging from · the ground by Weigelt et al. <1986> and Baldwin et al. <1986> rely on the use of the closure phase i.e. the sum of the visibility phases around a closed loop of baselines . The closure phase has been used for the last dozen years in VLBI for making diffraction limited images in situations whe...
متن کاملCamera phasing in multi-aperture coherent imaging.
The resolution of a diffraction-limited imaging system is inversely proportional to the aperture size. Instead of using a single large aperture, multiple small apertures are used to synthesize a large aperture. Such a multi-aperture system is modular, typically more reliable and less costly. On the other hand, a multi-aperture system requires phasing sub-apertures to within a fraction of a wave...

RESUME Hypertelescopes, or " multi-aperture densified-pupil imaging optical arrays" can provide direct images with full luminosity at arbitrary aperture dilution . They can be equipped with coronagraphic masks for difficult imaging situations such as the search for exo-Earths at infra-red and visible wavelengths . For detecting faint planets, down to 10 relative intensity, multi-stage coronagra...
متن کاملOptimal pupil apodizations of arbitrary apertures for high-contrast imaging.
In the context of exoplanet direct detection and characterization, where high-contrast imaging is mandatory, we present fully optimized two-dimensional pupil apodizations for which no specific geometric constraints are put on the pupil plane apodization, apart from the shape of the aperture itself. Masks for circular and segmented apertures are displayed, with and without a central obstruction ...
متن کاملExtraordinary infrared transmission through a periodic bowtie aperture array.
The discovery of extraordinary transmission through periodic aperture arrays has generated significant interest. Most studies have used circular apertures and attributed enhanced transmission to surface plasmon polariton (SPP) resonances and/or Rayleigh-Wood anomalies (RWA). Bowtie apertures concentrate light and have much longer cutoff wavelengths than circular apertures and can be designed to...
