The radiation is filtered using interference filters, focalised with an off-axis parabola, and injected into a single mode optical fiber (SMF; single-mode cutoff wavelength λc = 1.95 µm or 2.85 µm) providing modal filtering.
Tests of achromatic phase shifters performed on the SYNAPSE test bench: a progress report
Their positioning law, which is close to that of a Soret (or Fresnel) Zone Plate (FZP), causes focalisation by diffraction and interference.
Fresnel Interferometric Imager: ground-based prototype
Reconnaissance d’ob jets par focalisation et detection de changements.
Hierarchical testing designs for pattern recognition
The focaliser mirror was completely re-aligned, considering the wrong position of all of its tuning knobs and its obvious misalignment.
AMBER Task Force February 2008 run report
Doing the alignment of the focaliser we improved a lot the image quality of all the beams.
