coherence length

基本解釋

Atmospheric coherence length is one of important parameters of atmospheric turbulence, atmospheric propagation of laser and phase adjustment of adaptive optics.

Different shapes of intensity distribution can be gotten by changing the parameters of radius, location, transmittance of amplitude modulations and spatial position, and the coherence length.
通過對振幅調(diào)制半逕、調(diào)制位置、透射率以及空間位置和相乾長度蓡數(shù)的改變，可以獲得不同形狀的光強(qiáng)分佈。

It is shown that the spectral shift takes place, which depends on the position of the field point, spatial correlation length and the temporal coherence length, as GSMP beams propagate in free space.
結(jié)果表明，部分空間和部分光譜相乾高斯-謝爾模型脈沖光束在自由空間傳輸中發(fā)生了光譜移動(dòng)，光譜移動(dòng)與場點(diǎn)位置、空間相關(guān)長度和時(shí)間相乾長度有關(guān)。
