頻譜的分析在現今科學與科系中扮演極為重要的角色，透過頻譜的分析我們可以得知待測物的成分組成，或是表面形貌，從生物學、航空攝影、農業分析，都可以看到頻譜分析的作用，而高光譜能採集二維空間中的頻譜資訊，組成一個三維的高光譜數據，在許多領域的量測分析，高光譜扮演極為關鍵的作用。 現今的高光譜成像系統，有些製作技術困難且成本極高，或是量測極為耗時，並不利於現今普及且變動迅速的科學量測，本研究團隊致力於打造製作成本合理，且量測速度快的高光譜成像系統。我們透過編碼孔徑(Coded Aperture)以及閃耀光柵(Blazed Grating)兩個主要原件來實現一個量測迅速且準確的高光譜量測系統。在系統建構的過程中，我們透過三種雷射波段對系統進行波長定位，使用鹵素燈當作標準光源對系統中各種光學元件進行校正，並且在快照式與掃描式高光譜中各取其優勢進行結合，在量測時間與準確度進行取捨，以實現準確且迅速的高光譜量測系統。 ;Nowadays, the spectrum analysis plays an extremely important role in scientific community. Through the analysis of spectrum, we can know the composition of the object, or the surface morphology, which can be seen from biology, aerial photography, and agricultural analysis. Hyperspectral can collect spectrum information in two-dimensional space, which is different from the traditional spectrometer. Our research team committed to create a reasonable production cost and measurement High-speed hyperspectral imaging system. We use coded aperture and blazed grating to achieve a rapid and accurate hyperspectral measurement system. In combination, a trade-off is made between measurement time and accuracy to achieve an accurate and rapid hyperspectral measurement system.
