Various turbulence conditions , ranging from weak to strong , are considered as well as the dependence on turbulence strength , propagation length , wavelength , and the inner scales of turbulence are presented 計(jì)算結(jié)果表明,相位不連續(xù)點(diǎn)的數(shù)目不僅與描述光強(qiáng)起伏量的大氣湍流強(qiáng)度、傳輸路徑長(zhǎng)度和傳輸光的波長(zhǎng)有關(guān),而且還與湍流的內(nèi)尺度有關(guān)。
The computational results of strong scintillation with weak turbulence but long propagation length indicate that the number of branch points in distorted optical field has a tendency to saturation 另外,通過(guò)對(duì)湍流較弱但傳輸路徑較長(zhǎng)的強(qiáng)閃爍條件下畸變光場(chǎng)中出現(xiàn)的相位不連續(xù)點(diǎn)數(shù)目的計(jì)算發(fā)現(xiàn),當(dāng)湍流效應(yīng)達(dá)到一定程度時(shí),相位不連續(xù)點(diǎn)的數(shù)目有達(dá)到飽和的趨勢(shì)。
