論文在全面闡述了光學三維輪廓位相測量術的發展、應用現狀、研究熱點及未來發展趨勢的基礎上，簡要介紹了傅立葉變換和相移位相輪廓測量術的基本原理，對兩種測量方法存在的問題及誤差進行詳細分析和比較；針對位相解包裹錯誤點的傳播問題，作者通過改變解包裹路徑來提高位相解包裹的正確性；分析討論從解包裹位相（ x ， y ）到再現物體的高度h （ x ， y ）物理量之間的關系，研究相應的演算法，利用matlab平臺，對實際採集的條紋圖像進行處理和輪廓重構，其中改進及創新工作主要表現在以下兩個方面： （ a ）針對干涉型結構光場干涉條紋出現的漂移抖動對相移的影響，提出了一種用條紋穩定器穩定干涉條紋，用精密移動平臺使物體和ccd攝像頭同步移動實現等效相移的方法，建立了相應的測量系統，系統的條紋穩定可以達到。As to the video signal, alarm signal, control signal, are all weak electricity signal, exceedingly easily be subjected to the jam, in case the power supply system does not steady, wave propag ation is greatly, the harmonic content of power source overtops, the veins wave factors are great unduly, and even power source equipment breakdown, outputting abnormal, will be about to affect the video signal image effect, and dependability cuts downs to the security and alarming system. we adopt fast fu lye ' s mutation rule - fft alternatives, by the way of carrying fft alternatives to the local junction circuit, regulated power supply, ups ' s power source, and switch power source, thereby diagnose every degree harmonious wave content of power souse, and abnormal coefficient, compared to the normal working situation. thereby diagnose out the working condition of the regulated power supply, ups ' s power source, and switch power source
如果有供電系統不穩定、波動大，電源的諧波含量過高，紋波系數過大，乃至電源設備損壞、輸出異常等情況出現，將會嚴重影響視頻信號的圖像效果，大大降低防盜系統的穩定性和可靠性，我們採用快速傅利葉變換原理，即fft變換，通過對市電、穩壓電源、 ups電源、開關電源等的電壓信號進行fft變換，從而得出信號中各次諧波的含量及信號畸變系數，並將其與正常工況下的參數進行對比，從而進一步診斷出穩壓電源、 ups電源、開關電源等設備的運行狀況；組成監控系統的設備長期處于工作狀態，往往由於設備散熱條件不好、設備老化故障等原因導致設備表面溫度過高，從而影響設備的正常運行，降低設備的使用壽命。Starting with automation system, this paper, firstly, outlines the status of sensor lying in automation field and its developing state, shows the superiority about eddy current test by comparing it with the other nondestructive tests, expatiates the modern developing state about eddy current technology both here and there, shows the vista about eddy current test in our country and the background of the subject about the test for the width and thickness of stripe in the in - wall of cylinder after laser thermal treatment. secondly, beginning with maxwell equation in electromagnetic field theory and combining with some electromagnetic phenomena in real life, this paper explains qualitatively the operating principle about eddy current technology and the test theory for multi - parameter test with multi - frequency by math illation and gives some applying occasions about it
通過同其它幾種無損檢測技術的比較，給出了電渦流技術的優越性，闡述了國內外電渦流技術的發展現狀，展望了我國電渦流技術發展的未來，給出了汽缸內壁激光熱處理條紋厚度與寬度的檢測這個課題的背景；然後從電磁場理論中的麥克斯韋方程出發，通過一系列的數學嚴密推導，並結合現實生活中的一些電磁現象，定性地解釋了電渦流技術的原理，以及電渦流傳感器多頻率多參數的檢測原理，給出了電渦流技術的部分應用場合，以及電渦流檢測的等效電路。Heat treatment can also change the multi - layer ' s ( ticvti / tin / ti / ticb ) reaction coefficient. the reaction coefficient is decided by the exterior ticvs thickness, and influenced by the n perce ntage on the surface of the multi - layers -, the crystal status of tio2, and also influenced by the na + moved from the glass substrate
多層薄膜在300下熱處理lh時，薄膜的紫外一可見光透過率曲線與未熱處理時相比沒有改變;在400下熱處理1h時薄膜紫外一可見光透過率增大，並向長波方向移動;薄膜在500下熱處理時透過率增加，並出現干涉條紋。Zhang liji ( material physics and chemistry ) directed by professor xie xiaoming this paper is intended to solve problems for those who are designing, using pbgas. failure mechanism, as well as cycles to failure of two groups of pbga samples ( with / without underfill ) for thermal cycling conditions in the range of - 40 ~ 125, were presented. the experiment shows that solder ball in the samples without underfill cracked after 500 times cycle, no crack was found in the underfilled samples even after 2700 cycles
