dc.description.abstract本論文提出一個以快速傅立葉轉換為基礎的相位展開法則硬體電路架構,此相位展開硬體電路架構的功能在於加速數位全像顯微鏡(Digital Holographic Microscopy, DHM)的相位展開運算。本架構會依據一個以快速傅立葉轉換為基礎的相位展開演算法則來設計並且實作硬體電路以計算出一個最小平方誤差解(minimum squared error solution)。硬體架構中包含四個主要單元:轉換前單元、快速傅立葉轉換單元、轉換後單元以及嵌入式記憶體,在架構中利用嵌入式記憶體當作暫存空間搭配上其他三個單元的運算來達到加速電路計算的效果。為了驗證本論文提出的硬體架構的正確性,會將本硬體電路設計成客製化的電路放入system on programmable chip(SoPC)系統來實際上測量系統的效能。實驗的結果顯示本論文提出的硬體電路架構可以有效的減少相位展開運算所需要花費的時間以及硬體資源的消耗量,適合於設計嵌入式的DHM系統。zh_TW
dc.description.abstractThis paper presents a novel phase unwrapping architecture for accelerating the computational speed of digital holographic microscopy (DHM). An FFT-based phase unwrapping algorithm providing a minimum squared error solution is adopted for hardware implementation because of its simplicity and robustness to noise. The proposed architecture is used as a custom user logic in a system on programmable chip (SoPC) for physical performance measurement. Experimental results reveal that the proposed architecture is effective for expediting the computational speed while attaining excellent performance for designing an embedded DHM system.en_US
