1. Alias and Wavefront supply software for use in 3-D. 2. For many purposes, such a wavefront can be considered planar. 3. Each ridge blocks part of the wavefront , causing Fresnel diffraction. 4. In the geometrical optics case, this means that wavefronts cross. 5. In 1991, Wavefront introduced Composer, an image manipulation product. 6. First in 2006 for its Spherical Aberration Management and Wavefront technologies. 7. The two wavefronts are then superimposed, creating a fringe pattern. 8. The plasmon wavefronts can be directly controlled by adjusting antenna geometry. 9. The WaveFront View shows objects as a series of rings. 10. Theremins are also available from Wavefront Technologies in Los Angeles.
