Because color isochromatic fringes appear in the stress model based on a plane polariscope in white light , we studied the problems systematically by a digital camera as image inputting device , digital image processing technique and bp artificial neural network . based on the work that has been reported before , a technique named five - step color phase shifting technique ( fcpst ) to acquire single isoclinics is presented 根據白光入射時應力模型在偏振儀光學系統中的等色線條紋是彩色的特點,本論文采用彩色數碼相機作為數據采集與輸入設備,結合彩色信息圖像處理和bp神經網絡等新技術,對上述兩個難題進行了系統的研究,獲得以下成果:在綜合前人工作的基礎上,提出獲得全場單純的等傾角相圖的五步彩色相移法。

At the same time 7794m3 affusion test were processed , and roadbed settlement observation conducted for two more year , physical mechanism and chemical index experiment were analyzed in the laboratory , section experiment of earth sample was proceed , changement of compacted soil body micromechanism along with depth were analysed by polariscope and scan electricscope . drain ditch , barrel - drain and little bridge were treated by composite geotextile 在室內進行了物理力學、化學指標實驗分析,并對土樣結構進行了切片試驗,用偏光顯微鏡和掃描電鏡分析了土壤碾壓后沿深度分布的土體微觀結構變化情況,對邊坡、邊溝、排水溝、小橋涵及護坡封水采用復合土工布進行處理。

Three main error sources are the variation of intensities , the orientation errors associated with the configurations of the polariscope and the initial stress existing in the model . a quantitative method is presented to analyze and estimate the influence of different error sources on the final isoclinic results calculated by fcpst or the other pst 本文提出它們影響五步彩色相移法的定量誤差分析方法;提出控制各誤差的具體指標;給出了避免或降低這些誤差源影響的措施,為合理設計制造儀器、指導實驗和保證實驗結果的精度提供了依據。

Relevant theory is derived and explicit conditions for directly determining the isoclinic parameter in the range of [ 0 - 3i / 2 ] are given . a color camera records five isoclinic images coupled with isochromatics from a plane polariscope with five different settings in white light , respectively 其特點是在白光入射下平面偏振儀光學系統中,用彩色數碼相機采集包括背景光強在內的不同偏振場設置下的五幅彩色圖像,通過運算就可以得到[ 0 ? / 2 ]范圍內的等傾角。

The appearance and crystal structure change in the biodegradation of partially degraded starch granules were examined using sem technology and multifunctional polariscope 摘要利用掃描電子顯微技術和多功能偏光顯微技術系統研究三氯氧磷交聯淀粉在生物降解過程中的顆粒形貌和結晶結構變化情況。
