Currently they are fabricated by lithographic process, which is very expensive and time consuming since it is a several step process. the laser direct writing system is the kind of tool that exposes the precision patterns by the micro - spot on the photosensitive material
所謂激光直寫，就是利用聚焦的激光光束，由計算機控制聲光調制器的通斷以及平臺的移動，在光刻膠上進行曝光，經過顯影后得到所需要的圖形。In order to make the mgb more easy - operating, ultrasonic testing simula - tion software was designed and developed, which has a good user - oriented interface and can simulate easily the inspection fields of planar transducer, focused transducer and angle beam transducer. it also can help inspectors analyze the inspection procedures and predict the feasibility of actual ultrasonic testing, then choose suitable inspection parameters. the side - drill hole and flat - bottom hole are commonly used in ultrasonic
為了使多元高斯模型使用更加方便，本文設計並開發了基於多元高斯聲束理論的超聲檢測聲場模擬軟體，該軟體具有良好的圖形用戶界面，操作簡單，可方便地實現直探頭、聚焦探頭和斜探頭的檢測聲場模擬，可幫助檢測人員進行檢測過程的分析及結構件的可檢性預測，並選擇合適的檢測工藝參數。In order to deal with effect of the high damping, focusing probe with focused sound field is used in testing. the image device of ultrasonic c - scanning, which has functions of ultrasonic testing, pc - based control, data collection, data storage, data processing and image displaying together, is applied in testing for the sake of visual testing result
為了克服高阻尼影響，採用了具有聲束聚焦性能的聚焦換能器對不同形狀的該種復合材料工件進行檢測；為了得到直觀的檢測結果，運用了將超聲檢測與微機控制和微機進行數據採集、存貯、處理、圖像顯示集合在一起的超聲c掃描成像技術，並得到了工件內部缺陷的橫截面圖。This model is represented by a superposition of gaussian beams, and can simulate the wave fields of planar or focused transducers radiating at oblique incident through a curved fluid - solid interface. the mgb model is highly efficient and can be easily implemented on an ordinary personal computer
該模型是由一系列高斯聲束疊加而成，可模擬直探頭和聚焦探頭水浸檢測斜入射時的聲場分佈，計算效率高，易於在個人計算機上實現。Emphasized on the influence of planar reflector on focusing beams, the model of immersion focusing ultrasonic field based on focusing beams reflected by planar reflector is given. and it has been studied on immersion testing the cylindrical objects with the single focus transducer, which is available for small - diameter pipelines
分析了平面反射鏡對聚焦聲束的影響，首次建立了超聲聲束經平面反射鏡反射后的聚焦超聲場模型；分析表明，單焦距探頭經平面反射鏡反射后可用於小管道的智能檢測。The working range of acoustic imaging system is short generally. so focusing has to be taken into account, or the result will be bad
聲成像系統的作用距離通常都比較近，這種情況下就必須要考慮近場聚焦的問題，否則波束的指向性會老化。分享友人
