摘要
In a first exemplary embodiment of the present invention, an optical device comprises a telescope, a coronagraph device coupled to the telescope and having a focal plane occulting mask to provide a coronagraphic image, and a reticulate grid element arranged in a light path propagated through the telescope, at a location relative to the coronagraphic image, to create controlled fiducial spots in the coronagraphic image.
