New optical technologies have revolutionized astronomy, from the invention of the telescope 400 years ago to more recent developments of adaptive optics and segmented mirrors. The next disruptive ...

The PSF for astronomical telescopes and instruments depends not only on geometric aberrations and scalar wave diffraction but also on those wavefront errors introduced by the physical optics and the ...

Well, any of us who has ever looked through a telescope could say the same ... each of which comes into focus at a different point on the optical axis—hence the color fringes seen in refractors.

We have initiated a campaign to investigate the astronomical potential of the region in the optical/infrared. Here we report on an aspect of our campaign ... 2000, paper presented at the Atacama ...
