- The Cassegrainian unstable resonator has been demonstrated to be one of efficient means to decrease the OPO beam divergence. 证明了望远镜型共焦非稳谐振腔是压缩OPO光束发散角的有效方法。
- Beam Divergence As through the air telecom signal go further, they diverge. Beam divergence measures that divergence. 波束发散度当电信信号穿过空气向前传播时,信号将发散。波束发散度用于衡量这种发散。
- By giving the optimum reflectance finesse, the maximum beam divergence and minimum aperture of the Fabry-Perot interferometer can be obtained. 由最优反射精细度可得到入射到标准具光束的最大发散角和标准具的最小通光口径。
- 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。
- It is used in the measurement of ranging accuracy,maxmun and minimum ranges,pulse energy,pulse width,repetitive frequency features,beam divergence and optical axis stability of LRF. 主要检测测距机的距离准确性、最大及最小测程、脉冲能量、脉宽、重频特性、束散角及光轴稳定性等。
- The results show that the effects on the output laser wavefront of the FADW are mainly the beam deflexion and the beam divergence, the other high-level wavefront errors are very low. 结果表明,自由旋涡气动窗口对输出激光波前的影响主要是光束偏转和离焦,特别是气动窗口工作在设计状态时,其余低阶及高阶像差都比较小,能够满足实际需要。
