spot-size error

常见例句

The spot shape and size are determined to minish the sub-pixel centroiding error caused by the distortion of the point spread function due to the pixel sampling effect of the CMOS APS.
確定光斑形狀和大小的依據是，減小由於探測器像元對光斑能量分佈的採樣導致點擴散函數變形，從而引起的利用亞像元技術求星像中心的計算誤差。
Based on the model of star point and error calculation mode, the deviation of sub-pixel centroiding due to the size of window, the variance of spot and the noises of APS are analyzed theoretically.
根據星點模型和質心誤差計算模型量化分析了窗大小、星點模型方差、噪聲源對APS亞像素質心定位的影響。
