空心光錐 的英文怎麼說
中文拼音 [kōngxīnguāngzhuī]
空心光錐
英文
hollow cone-
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 high - voltage isolation optocoupler has been developed successfully, and its characteristics have been analyzed, it has some excellent merits, such as simple structure, working on stable status and high speed and so on. it will be extensive applied in high - voltage working environment extensively. 3 ) adopt hollow taper cavity to conduct the light in order to improve the stability and reliability of the high - voltage isolation and linearity optocoupler that can ’ t run very well
3 、針對高壓隔離線性光電耦合器的穩定性、可靠性不佳的狀況進行研究，提出了解決辦法，設計了空心錐腔進行導光，研製出了高穩定性、高可靠性的高壓隔離線性光電耦合器，對該器件的性能進行了分析，與改進前相比，穩定性、可靠性都有較大提高。
