英文
insert cover-
In the first part of this paper, the theory of laser range and dds technology was introduced, the factors of influencing range precision were also analysed. at the same time, put forward in the paper, with using the fpga embedded technology, the wideband and high resolution sin modulating signals can be generated easily, then analysed the noise of the dds ; in the second part, the theory of phase measurement based on fft was analysed. in the phase range system, by using the fft operation, the resolution and sensibility of phase measurement can be enhanced ; then some circuits were designed and come true, also simulated and validated ; in last part, the improvement of the phase range system was brought forward, summarized and expected
論文首先闡述了激光測距和調制信號源的基本原理，分析了影響測距精度的因素，指出應用dds技術可以實現寬帶、高精度的調制信號輸出，說明了引起dds輸出信號雜散的原因和解決的辦法;同時分析了應用fft運算實現信號相位提取的基本原理及設計方法，採用這種檢相技術，可以極大地提高測相精度與靈敏度;然後提出了基於fpga嵌入式系統的相位式激光測距機的整體設計，並就各部分進行了詳細的分析與設計;接著介紹了激光測距系統的外圍電路和基於quartusii集成軟體平臺的部分硬體電路的設計，並對其中的設計進行了模擬和驗證;最後總結提出了對系統今後的進一步改進和完善的思路。When developing an embedded project that requires standarc peripheral devices, the well - defined interface - - the universal serial bus with various connectors, protocols and cables being unified into, will improve the whole system ' s stability and integrality
開發一個帶多種外圍設備的嵌入式系統，如果選擇通用串列總線（ usb ） ? ?一種具有標準連介面，標準協議和標準連接線的通用協議，作為設備介面的話，將大大提高整個系統的穩定性和整體性。
