  1. In the experiment, we use the he - ne laser and the semiconductor laser as the source, record the bessel beam patterns behind the axicon by using a digital camera and a microscope, measure the radius of the bessel beam central spot by film - scanning and measure the effect of both the radius of the aperture and the open angle of the axicon on the maximum non - diffraction distance. the experiments show that a specific propagating range has constant power and the beam has a bessel - like distribution in this range. the results agree with the beam corresponding to a diffraction free beam

    同時我們還採用膠片掃描的方法測量了無衍射光束的中心光斑尺寸，測量了不同光闌孔徑和不同稜角情況下的最大無衍射距離和傳播軸附近橫截面內微小光孔中的光強，實驗結果顯示當激光光束經過軸棱錐轉換後有一段距離功率變化很小，且分佈近似貝塞爾分佈，符合無衍射光束的特性;經過聚焦后，呈現三維分佈中空的光束bottlebeam ，實驗結果與理論分析基本吻合。
  2. In computation of swept volume approximation, an improved technique to generate the swept volume approximation for arbitrary meshes is presented by introducing generator simplification and path resample using frenet moving frames along the discreted sweeping trajectory. other steps, such as a directed distance field computation on a uniform grid based on the hardware accelerated computation technique and iso - surface extraction using marching cubes algorithm, are also included in this algorithm. in addition, the simplification scheme and smoothing technique are applied to the swept volume generated from iso - surface extraction

    本文的主要貢獻在於：在掃描體逼近計算方面，在原有任意多邊形網格模型沿任意路徑運動生成掃描體逼近演算法的基礎上，提出了加入對掃描母體簡化的預處理和用活動標架對掃描路徑進行重采樣等過程，演算法的其它過程還包括：計算掃描體中幾何基元的排列，用硬體加速構造無符號的有向距離場，將無符號距離場轉化為有符號距離場，從有符號有向距離場提取等值面等。
  3. 3 - d laser scanning technique is a way that uses laser pulse to scan the object to get the superficial characteristic information of the entity. it applies to the close quarters or middle distance scene of the objects in the real world. 3 - d laser scanner has its outstanding performance in this field

    三維激光掃描技術是其中一種利用激光脈沖對物體表面進行掃描從而獲取其表面特徵信息的技術，它適用於中近距離的寬場景、大物體的快速高精度掃描，為建立場景的三維模型提供了必要而且準確的工具。
  4. One image shows a house under close observation in a palm grove in iraq ; another shows a road being scanned for hidden bombs

    其中一張圖案中是伊拉克棕櫚樹林中被近距離觀察的一所房屋；另一張圖案則顯示出被進行隱藏炸彈掃描的一條道路。
