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。 -
The technique core of the 3 - d outline tracking scan lies in the adoption of several photoelectric sensors, laser measuring sensors and super voice wave measuring sensors to carry on probing, the single chip makes the photoelectric signal examined as the control basis, and controls the step motor to drive measurement machines and probing sensors to make outline tracking and scans movement along high and breadth direction of the vehicle, and record its outline track, and the data measured is delivered to the computer, finally, acquires the size of the vehicle checked through the place of computer data processing
三維輪廓跟蹤掃描技術的核心在於採用多套光電傳感器、激光測距傳感器、超聲波測距傳感器進行探測，單片機把檢測到的光電信號作為控制依據，控制步進電機驅動測量機及探測傳感器在車長、車高和車寬方向上作輪廓跟蹤掃描進給運動，記錄其輪廓軌跡，並把測得的數據傳送到上位機，經上位機數據處理獲得被檢車輛的特徵尺寸。 -
Take a photograph of devices hav developed from dante spectrometer to soft x - ray str eak camera ( at ~ 20ps ) in which one has a chance to investigate a good many plasma phenomenon. measurement of the time - varying spectral shape of the soft x - ray continuum from laser - fusion targets can provide a detailed dynamical record of x - ray processes important to the understanding of thermal conditions in such experiments
自從六十年代末到七十年代初以來，應激光聚變實驗研究的需要，軟x光時間分辨診斷技術有了長足的發展，攝譜裝置由以前的dante譜儀到現在的軟x光條線相機， （ t 20ps ） ，通過這些裝置，可以有機會驗證諸多等離子體現象。 -
First, we can use a camera to take over the laser beam at one end, record the position of the light - spot, and calculate the centroid of the light - spot, then, move the laser on the guide rail. we should rectify the screw until the position of light - spot is unchangeable. then, the camera should be moved to the other end of the guide rail
先用攝像機在一端接收激光器發出的光斑，並記錄光斑的位置，求出其質心，然後在導軌上移動激光器，調節頂絲，直到攝像機上的光斑位置不動為止，然後將激光器移到導軌另一端，讓激光器在導軌上滑動，調節頂絲，直到攝像機上光斑位置不變，而且與前一次測試時的位置在誤差允許的范圍內，則認為激光器直線性校準完畢。 -
A team from france and the netherlands set a new speed record for subdividing the second, reporting last year that a laser strobe light had emitted pulses lasting 250 attoseconds ? that ' s 250 billionths of a billionth of a second
去年，法國與荷蘭合組的研究團隊創下新紀錄，根據他們報導，一束頻閃雷射光發射的脈沖，只持續了250阿秒（ 10 - 18秒） 。
