碩士 === 國立中央大學 === 光電科學與工程學系 === 105 === 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.
