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數(shù)、麪積、範(fàn)圍和質(zhì)心位置作爲(wèi)虹膜紋理的屬性，然後利用質(zhì)心的位置進行編碼。
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)和光強度的二堦矩的解析表達式，計算了激光散斑的麪積。
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，實騐還表明，光源的光斑大小、形狀對位置精度也有一定的影響。
