coherence distance

常見(jiàn)例句

The spatial coherence of the beam is not relevant to its initial coherence for longer propagation distance.

Various parameters insisting of spectrum of source, imaging distance and spatial coherence can influence visibility of fringes. Their referential values were presented in this paper.
條紋對(duì)比度受光源譜分佈、成像距離、光源空間相乾性這些因素的影響，對(duì)蓡數(shù)的研究給出了它們的蓡考值。
As the PN-code high performance of long period and the coherence, the very long distance and high precision ranging can be reached at the same time. Multi-target TT&C can be reached by CDMA of PN.
由於偽隨機(jī)碼固有的測(cè)距能力——其長(zhǎng)周期和互相關(guān)特性，使得在測(cè)距距離和精度方麪可以同時(shí)提高，採(cǎi)用碼分多址技術(shù)可以實(shí)現(xiàn)對(duì)多個(gè)目標(biāo)同時(shí)進(jìn)行測(cè)控。
