21. An additional important characteristic of the modulator is its optical wavefront quality. 22. The mean wavefront perturbation in each pixel is calculated. 23. In the zebrafish, segmentation is coordinated by the clock and wavefront model. 24. Once the subject is properly placed, wavefront correction and imaging takes place. 25. A common method is the Roddier test, also called wavefront curvature sensing. 26. Much of the path between stations'wavefronts was over highly conductive seawater. 27. Wavefront acquired rival computer graphics company Thomson Digital Images of France in 1993.28. The frequency determines how many wavefronts are both entering and leaving the boundary. 29. Figure " rays and wavefronts " illustrates this relationship. 30. Under Laplacian ) of the phase of the wavefront .
