scanning spot 中文意思是什麼
scanning spot
解釋
掃描點-
The visx star star 4 combines the technologies of customvue wavescan aberrometer, activetrak 3 - d active eye tracking, iris registration, variable spot scanning and variable repetition rate to provide customized wavefront treatment. in the past, standard lasik corrects refractive errors, such as myopia, hyperopia and astigmatism which are so - called low order aberrations
威視visx star 4是結合前波前像差分析儀3d眼球主動追蹤系統虹膜定位系統ir iris registration及智慧型超微光斑等技術去提供個人化激光矯視療程。在過去，標準lasik可解決近視遠視及散光等所謂低階像差問題。 -
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 small scanning - spot excimer laser corneal system was developed based on flying - spot scanning model
摘要以飛點掃描切削模式為基礎，研製小光斑飛點掃描準分子激光角膜屈光矯正系統。 -
An electron beam, forming a scanning spot on the signal plate, zigzags its way, line by line, across the plate.
在信號板上形成掃描點的電子束，逐條地曲折掃過信號板。 -
Based on the relationship between the change of the cornea thickness and optical path length, the ablation profile for the correction of wavefront aberration is presented and simulated on computer. the process of scanning - spot excimer laser is studied and simulated on computer. models for calculation of residual wavefront aberration on situations of lateral decentration and torsional misalignment are brought up
使用改變光程的方法建立起波前像差與角膜切削量之間的關系，並對像差矯正模型進行計算模擬;深入研究了小光斑準分子激光飛點掃描模型，對飛點掃描過程進行計算模擬;提出了中心偏移和旋轉情況下剩餘像差計算模型，為定量研究切削中心定位精度對像差矯正的影響提供了依據。 -
Ornithologists rely on bird - watchers to keep track of changing patterns of migration, astronomers have long profited from enthusiasts scanning the skies to spot new comets, and archaeologists benefit from amateurs ' finds
鳥類學家依賴于觀鳥者們跟蹤鳥群遷移而不斷變化的方式，天文學家長久以來也從科學狂熱者觀視天空並發現新的彗星而受益匪淺，而動物學家也從業余愛好者的發現中受益。 -
You ' ll hopefully spot anyone blatantly standing in a window, so that means that you should focus your attention on scanning the edges to ensure that noone is ' tucked - in ' to the window
你很希望一眼就發現任何人站在窗戶旁，這樣你就得集中精力搜索窗戶的邊緣，以免你們被房裡的人「通吃」 。 -
Scanning - spot camera
