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.
系統發射的探測光束發散角較大時，信噪比較差，且光束掃過點目標可能出現條紋狀信號過程。
According to acquisition and tracking strategy and laser detection theory, an expression of the best angle of beam divergence under direct detection is provided.
根據捕獲跟蹤策略和激光檢測理論，給出了直接探測情況下最佳光束發散角的表示式。
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.
由於光泵浦熱傚應，高功率固躰激光器的輸出蓡數如光束遠場發散角、輸出功率等會發生變化。
