The relationship between wave - front aberration and focal spot size was researched roundly, and the essential connection between focal spot energy shape and wave front gradient distribution was discovered, and a smarter parameter to evaluate wave front aberration was founded. based on this, the wave front aberration tolerance confined by focal spot size requirement was obtained through calculation and statistics method. 2
比較全面地分析了系統內部波前誤差與光束焦斑尺寸之間的關系，找到了波前梯度分佈與焦斑能量分佈之間的本質聯系，提出了一個與焦斑尺寸關系最密切的波前誤差參數，並採用數值模擬和統計的方法得到了焦斑尺寸限制條件所要求的波前誤差限制條件； 2 -
The reasons focusing only on ray travel times are " noise tolerance could be enhanced and the sensitivity to the environment model mismatch may be reduced by neglecting amplitude information ; phase ambiguity is eliminated by employing the group delay of arriving wave packets ; travel times are pseudo - linear functions of sound speed profiles of the medium, and the perturbation of ray travel time is much smaller than sound pressure ' s
之所以選擇聲傳播時間的原因是：噪聲容限可以得到提高，並且傳播時間的計算可以不考慮聲壓的信息，從而降低了對環境模型失配的敏感性；相位的起伏也可通過到達包絡的群延時來消除；傳播時間是介質聲速分佈的偽線性函數並且傳播時間的起伏遠小於聲壓的起伏。 -
Multimode interference ( mmi ) couplers based on the self - imaging effect are rapidly getting popular because of the advantage of low loss, compact size and large fabrication tolerance. the thesis studied the principle of the mmi coupler. the optical field distribution in the multimode wave - guide is modeled by eim and mode propagation analysis method ( mpa )
