不同於市售儀器量測耗時，超快速光分佈量測儀利用屏幕複合式成像系統一次擷取大範圍光強分佈，並結合待測物旋轉系統以拍攝不同角度之光強分佈，最後透過本團隊所開發之影像融合系統，可快速取得待測光源之配光曲線。 為了對光源進行色彩分佈分析，在基於此儀器之架構下，本論文提出了空間多工之新型屏幕設計，並在相機鏡頭前裝上特殊穿透式光柵，以實現高光譜成像之功能。本論文對高光譜成像量測系統提出了一套影像融合演算法，並針對系統之波長定位、均勻度校正及頻率響應校正皆提出了解決方案。在未來，本儀器僅需透過更換屏幕，與光柵的使用與否，即可在短時間內同時量測光源之強度與色彩分佈。 ;In contrast to commercialized machine that have time-wasting measurement issue, Ultrafast Optical Goniometer (UOG) utilizes Screen Imaging Synthesis (SIS) system to acquire a wide range of optical distribution in one-shot. Combining Object under Test (OUT) system, the SIS system can capture different angle of light distribution. Finally, by using the imaging fusion algorithm developed by our team, light distribution curve can be acquired in short period of time. In order to analyze color distribution of a light source, this thesis proposes a new screen design with spatial multiplexing, and arranges a special transmitting grating in front of the lens to achieve the Hyperspectral Imaging (HSI) measurement. This thesis proposes an imaging fusion algorithm for HIS measurement, and offers a solution for wavelength calibration, uniformity correction and frequency response correction. In the future, UOG can rapidly measure the intensity and color distribution of a light source, through the screen changing and the using of grating.
