摘要

光譜影像由於同時具有同時呈現外部空間(Spatial)資訊與內部光譜(Spectral)資訊之特色，近年來逐漸被用在醫學檢驗及食品安全。本研究針對自行開發之超分光光譜影像系統，應用BCB撰寫動態拍攝程式並進行光譜強度校正。該超分光系統包括CCD檢測器、單光儀、照明光源與影像擷取卡，拍攝波段涵蓋400 ~1100 nm，解析度達0.29 nm。本研究探討建立控制程式進行連續拍攝，以取代原來的手動拍攝，並針對影像拍攝、影像擷取及影像重組等方面進行兩者的比較，結果透過標準影像的色階分佈強度檢定分析，顯示兩者並無顯著差異(=0.05)，但作業時間上連續拍攝可節省約22倍的時間，並可避免操作上人為的疏失。

This study applied the ultraspectral imaging system that developed by our teams to test its image taking in continuous mode by BCB program and arries on the intensity calibration. The improvement and examination efficiency were also discussed. The ultraspectral imaging system consists of CCD detector, monochromator, light source. It scans the wavelength from 400 ~1100 nm with a resolution of 0.29 nm. The results show that continuous mode has not significant difference (=0.05) in intensity distribution with manual mode, but the former mode could save 90% operation time. Meanwhile the continuous mode has advantage in image acquisition, and image reconstruction of less error.
