近幾年來，結構性光場研究在光學應用領域中有所提升，像是在自動光學檢查或是汽車工業。傳統雷射的波長多以增益介質特性來決定其波長範圍，其雷射波長無法任意更改，也使其應用層面較為受限。超連續雷射光源具有與傳統雷射相同的高相干性卻有別於窄光譜的特性，寬光譜的超連續雷射光源擴大了雷射在結構性光場應用的創新和市場潛力。有鑑於此，本論文的研究目的在於使用超連續雷射光源以圓孔繞射原理所產生的圖騰，以了解是否可產生清晰的準晶格之結構性光場。此外，藉由超連續雷射之寬光譜特性，不同的透鏡焦點在不同波長而產生不同顏色之準晶格圖騰的關係進行探討。最終，針對超連續雷射在可見光波長下所產生準晶格的結構性光場，也就是結構色的光學物理現象呈現本文的結論。

During the last years, the utilization of structured light field is increased in optical applications, such as auto optical inspection or automotive industry. The wavelength of tradition laser was decided by gain medium and which is can’t altered directly so that limit the application area. The supercontinuum laser can be one of the solutions for development. It still shows coherence in supercontinuum laser but different from tradition laser in narrow-spectrum characteristics, supercontinuum laser with broad-spectrum characteristics which is the benefit to extend the innovation and market scope of structured light field. In this research, the diffraction pattern was formed by using supercontinuum laser beam projected onto the plate after the light passed through the circular aperture and expect to capture clear image of quasicrystal structured light field patten. Furthermore, the correspondence of different color patten between wavelength and focus point of lens based on the broad-spectrum characteristics of supercontinuum laser. Taken together, my works demonstrate that the quasicrystal structured light field and the related observation of physical phenomenon can be generated using supercontinuum laser.
