內容簡介

　　"Stochastic optimization in continuous time"（AuthorFwu-Ranq Chang）is a rigorous but user-friendly book on the application of stochastic control theory to economics. A distinctive feature of the book is that math-ematical concepts are introduced in a language and terminology familiar to graduate students of economics.

無需波前傳感器的像清晰化技術在不需要波前傳感器的條件下，以成像清晰度和接受光能量為性能指標直接作為算法優化的目標函數，優化得到接近理想的校正效果，係統復雜性大大降低，比較適閤用於補償大氣湍流帶來的閃爍現象。

第三：由於無需波前重構，大氣湍流帶來的閃爍不影響算法的迭代以及反饋裝置的數據采集，在大氣湍流較強或光束長程傳輸應用中有其獨特優勢[3]。
