They indeed showed the concave curvature of the wavefronts that were propagating away form the gold nanorod, exactly as predicted by theory," says Rainer Hillenbrand, Ikerbasque Professor at nanoGUNE, who led the work.
Objective wavefront refraction is based on fitting a reference wavefront produced by an optimum, spherocylindrical lens to a two-dimensional ocular wavefront aberration function measured for a subject's eye.
The complex amplitude of a wavefront obtained by a uniformly collimated monochromatic beam of light reflected from an object is given by
The investment banking firm Aronson Capital served Wavefront as an advisory services provider.
Let E([r.sub.i], [r.sub.S]) be the range compressed SAR raw data with the assumption of planar wavefronts. After projecting [rho] to [r.sub.i], we can get
Velocity was calculated to find the trend and make wavefront maps of stress waves.
However, it is also found that the interface of the growing wavefront broadens in time rather than being a constant width, as predicted by MFT.
By comparing the image of Zeta Ophiuchi with the predictions illustrated above, one can infer a wavefront error of about 1 micron for the 4-meter telescope.
Another way to look at how telescopes produce images from distorted wavefronts is to imagine each subaperture as being imaged independently by the corresponding subaperture of the telescope.
The real star and the artificial "guide star" permitted simultaneous measurement of the two wavefronts. Even without bringing adaptive optics into play, we would learn whether the wavefront distortions from the two very different point sources were similar enough for the technique to work.
