beam divergence

基本解释

For large probe beam divergence the SNR is relatively poor, and even a streaky signal process is predicted if a point target is scanned across.
系统发射的探测光束发散角较大时，信噪比较差，且光束扫过点目标可能出现条纹状信号过程。
According to acquisition and tracking strategy and laser detection theory, an expression of the best angle of beam divergence under direct detection is provided.
根据捕获跟踪策略和激光检测理论，给出了直接探测情况下最佳光束发散角的表示式。
The output parameters such as beam divergence angle in far-field output power of high power solid state lasers are variable due to thermal effect of optical pumping.
由于光泵浦热效应，高功率固体激光器的输出参数如光束远场发散角、输出功率等会发生变化。
