使焦 meaning in English
parch
Examples
- In general , the lens chromatic aberration and the group velocity dispersion lead to a broadening in the temporal and spatial intensity distributions at the focal plane and a decrease o
一般说来，透镜色差和群速度色散会使焦平面上脉冲光束的时间、空间光强分布展宽，峰值光强降低。 - In practical application , due to the parameter accuracy of two point temperature correction is limited by readout circuit noise 、 dynamic range 、 analogue to digital converter word length and calculating noise , the performance of focal plane array detector is not the performance it should be
目前实用性较好的两点温度定标法的校准系数精度受读出噪声、信号动态范围、模数转换字长和运算噪声的限制，很难使焦平面探测器的空间残留噪声达到应有的精度。
