speckle size

基本解釋

In this paper, the number, size and center of the iris' speckle regions are considered as the properties of iris texture.
本文將虹膜散斑的個(gè)數(shù)、面積、范圍和質(zhì)心位置作為虹膜紋理的屬性，然后利用質(zhì)心的位置進(jìn)行編碼。
Analytical expressions for the first-and second-order moments of the intensity have been derived, and the size of the speckle cell has been computed.
導(dǎo)出了散射光場的自相關(guān)函數(shù)和光強(qiáng)度的二階矩的解析表達(dá)式，計(jì)算了激光散斑的面積。
At the same time, the experiments also show that the size and shape of the light speckle can also exert certain effects on the ultimate position precision.
同時(shí)，實(shí)驗(yàn)還表明，光源的光斑大小、形狀對位置精度也有一定的影響。
