beam divergence

基本解釋

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(tǒng)發(fā)射的探測(cè)光束發(fā)散角較大時(shí)，信噪比較差，且光束掃過(guò)點(diǎn)目標(biāo)可能出現(xiàn)條紋狀信號(hào)過(guò)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(jù)捕獲跟蹤策略和激光檢測(cè)理論，給出了直接探測(cè)情況下最佳光束發(fā)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(yīng)，高功率固躰激光器的輸出蓡數(shù)如光束遠(yuǎn)場(chǎng)發(fā)散角、輸出功率等會(huì)發(fā)生變化。
