Fig. 3From: Asymmetric dihedral angle offsets for large-size lunar laser ranging retroreflectorsFar-field diffraction patterns simulated for a 200-mm diameter, circular aperture, hollow-type retroreflector when a green 532-nm laser is assumed for the incident beam. The three dihedral angles (δ1, δ2, δ3) of the retroreflector are set to (0, 0, 0) in graph (a), (0.35, 0.35, 0.35) arcseconds in graph (b), and (0, 0.65, 0) arcseconds in graph (c).Back to article page
