phase aberration meaning in English

相位差

Research on phase aberration of ultrasonic phased array echo signal
超声相控阵回波信号相位偏差的研究
At last the laser beam with simple aberration , such as no phase aberration and low order zernike phase aberration , is analyzed
最后，对无相位畸变和存在低阶泽尼克相位畸变情况下的简单畸变光束进行了相应的分析讨论。
The resolution of optical system can not reach its diffraction limit because of the phase aberrations caused by atmospheric turbulence and other wavefront errors . adaptive optics technology uses deformable mirrors to perform dynamic phase modulation and endow optical system the ability to decrease the influence of dynamic wavefront errors
大气湍流等动态干扰使光波面相位发生畸变，使光学系统的分辨率无法达到其衍射极限，而自适应光学系统使用变形镜对光波面进行动态相位调制，赋予了光学系统能动可变的能力而有效地解决了动态干扰的问题。
