Such as, the amplifying effect on the field of divergent spherical wave, the condition of talbot effect to be observed, etc. based on the study of the law and method to generate structured illumination, which is derived from fresnel diffraction law, this thesis offers a structured illumination scheme that is applicable to 3d sensing system. also, computer simulation and 3d shape measurements of real objects are presented
在研究了基於菲涅耳衍射的結構照明的原理和方法的基礎上，本文提出了適用於三維傳感系統的結構照明方案，並通過計算機模擬實驗和對實物模型的三維面形測量證實，本文提出的原理和方法是正確的和有效的。 -
Here, the spatial distribution of fresnel diffraction field and different talbot effects of sinusoidal grating are presented, under three different illuminating conditions. especially, we discussed some interesting properties about fresnel diffraction field and talbot image, when sinusoidal grating is illuminated by divergent spherical wave
特別地，我們討論了發散球面波照明的情況下，菲涅耳衍射光場和泰伯像所具有的一些有趣的性質，如球面波對光場的放大作用，泰伯效應存在的條件等等。 -
The principle advantages of vcsels over conventional edge - emitting lasers lie in ultralow threshold current, small far - field divergent angle, high modulation frequency, potential for wafer level testing and the ease for single longitudinal mode operation and two - dimension integration. as a result they show considerable promise for applications such as optical fiber communication, parallel optical interconnects, optical information processing and neural networks, etc. a direct coupling theoretical model in quasi - three - dimension for the gain - wave guide vertical - cavity surface - emitting lasers has been created in this paper
它與傳統的邊發射激光器相比具有更優越的特性，例如，具有極低的閾值、較小的遠場發散角、調制頻率高、易實現單縱模工作和二維集成，無須解理封裝即可進行在片測試等，所以，它被廣泛應用於光纖通訊、并行光互聯、光信息處理、光神經網路等領域。 -
It shows that when walk - off and diffraction effects could be ignored approximately estimation of the phase distribution of second - harmonic wave could be done. the far field divergent angle and second moment radius of harmonic wave will vary with the aberration of fundamental wave, but the far field divergent angle will be obviously smaller than that of fundamental wave. the phase distribution of both fundamental and harmonic wave is measured using hartmann - shack wave front sensor in the experiment with 1064nm and 790nm lasers, respectively
這說明利用非線性光學頻率變換方法拓寬波前傳感器件的響應波段是很難實現的，但是，通常三波相互作用過程的研究均是建立在平面波和理想高斯光束之上，因此我們對于位相畸變倍頻過程的研究是非線性光學領域一個重要而有意義的新課題，它有助於人們更加深入理解非線性光學效應，為進一步合理利用之奠定了理論和實驗的基礎。
