Word of the Day: Apodizing

Via PC Gaming Tips, “An apodizing phase plate coronagraph for VLT/NACO”:

Abstract: We describe a coronagraphic optic for use with CONICA at the VLT that provides suppression of diffraction from 1.8 to 7 lambda/D at 4.05 microns, an optimal wavelength for direct imaging of cool extrasolar planets. The optic is designed to provide 10 magnitudes of contrast at 0.2 arcseconds, over a D-shaped region in the image plane, without the need for any focal plane occulting mask.

Apodizing, of course, means “if you take cool extrasolar planet pictures with our coronagraph, they’re sure to end up on APOD.”
