wave front in English
Aspheric surfaces tend to create wavefronts that beat against one another, the changes in one negating the effects of another.
Use "wave front" in a sentence
1. Wave front aberration measuring device
2. For wave-front guided corneal surgery, measuring higher order monochromatic aberrations in mydriasis is needed.
3. Wave front aberration of the projection optical system is measured from the state of the interference fringe.
4. The phasing plug provides an approximately flat acoustic wave front from the compression driver to the horn.
5. The transducer produces a radially dispersing acoustical wave front, heating the adjacent tissue and forming a thermal lesion therein.
6. An optical system can be considered to be performing at its best when it is free of aberrations such as wave front distortions.
7. The aberrometer is simple to use-one of its major innovative features, and allows customisation of corneal ablation procedure to measure wave-front data.
8. Calibration of a diffractive compensation or absolute normal element (twin or dual cgh) by means of wave front errors of the spherical auxiliary wave
9. The determination of position and strength of the different shock sections (plane, slightly curved, circular) can be reduced approximately to two-dimensional problems. These problems arise in planes normal to the respective wave front in acoustic approximation.
10. When either a plane acoustic wave or a weak shock wave is incident upon an infinite wall, the boundary-layer correction to the reflected wave becomes large if the angle between the wave front and the normal to the wall approaches zero.
11. To prevent destruction of the inlay (14) by the incoming shock wave, and hence to ensure the formation of a projectile or of a Munroe effect, a layer (15) which flattens and deadens the shock wave front and whose acoustical impedance is less than that of the inlay (14) is arranged in front of the inlay (14) on the side nearer the explosive.
