  1. Satellite laser altimeter return waveform is sensitive to the vertical canopy structure and the change of underlying ground elevation. it is optimal for mapping forest structure. the return waveform and the processing method are described. the relationship between laser waveform and canopy structure parameters is explored ignoring the clumping effects. the clumping caused that structure parameters are different from the actual value. to solve this question, a model by 3 - d canopy structure parameters is needed

    星載測高儀的回波信號能夠靈敏反映地面植被組成和地表高度的化,因此能夠用於探測森林地貌;首先對星載測高儀的森林回波信號及其處理方法進行了介紹,探討了在不考慮植被集情況下,植被組成與回波信號之間的關系;由於植被的集效應,例如樹葉群集成樹冠,會導植被組成參數與真實值之間存在差異,這需要建立關於三維的空間分佈模型加以解決。
  2. For single lens, the change of beam quality lead to the varity of dimension and positions of spot of focused nd : yag laser. a telescopic system can produce constant dimension and position of beam waist

    束質量的化導了單透鏡的束的束腰大小和束腰位置都發生化,採用望遠鏡耦合系統可以得到大小和位置都不的像方束腰。
  3. Based on the rate - equation theory of four - level system, the expressions of threshold pump power, output power and slope efficiency are given. the influence of space distribution of pump light ( the position of focusing point, dimension of pumping light and divergence angle ) to the output characteristics are also discussed. then, by investigating the effects of thermal effect of laser crystal on the size of laser cavity mode, we obtain the mode - matching principle of high power laser diode end - pumped solid - state lasers

    其中,在泵浦的空間分佈量中我們分別考慮了泵浦焦后的腰斑大小、焦腰斑在增益介質中的位置以及泵浦在介質中發散角的影響;然後我們研究了在高泵浦功率下晶體因吸收泵浦而產生的熱效應所導的熱透鏡效應以及熱衍射損耗,通過分析它們對振蕩腔模尺寸的影響,得到了高功率半導體二極體端面泵浦固體器模式匹配的要求,為高功率連續單頻nd : yvo _ 4器的優化設計提供了理論依據。
