内容简介

　　"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.

第一：由于不需要进行波前测量，系统中不需要采用波前传感器，也无需进行波前重构，而是以成像清晰度和接受光能量为性能指标直接作为算法优化的目标函数，降低了系统和算法的复杂性[3]。

无需波前传感器的像清晰化技术在不需要波前传感器的条件下，以成像清晰度和接受光能量为性能指标直接作为算法优化的目标函数，优化得到接近理想的校正效果，系统复杂性大大降低，比较适合用于补偿大气湍流带来的闪烁现象。

由于星地链路之间的主要传输介质是大气，穿过路径较长，大气分子对于激光光束的吸收与散射将引起传播方向上光能的衰减，因此传输信道中的大气湍流是限制通信距离及通信系统性能的瓶颈之一，不仅需要考虑大气对激光的吸收与散射，还必须考虑大气的湍流效应。大气湍流会使光载波在传输过程中随机地改变其光束特性，致使携带信息的光波的强度和相位在空间和时间上都呈现随机起伏，造成闪烁现象，极大地降低了系统的成像质量或光束质量。基于随机并行下降算法的自适应光学技术可以提高激光作用到目标上的聚集程度；降低空间目标在望远镜成像面上的模糊程度，提高目标识别的准确度，实现对目标的精跟踪；提高激光通信系统的载波光束质量，降低系统的噪声水平、提高数据传输速率等，在天文自适应成像领域已得到成功应用。

评分☆☆☆☆☆

还是很不错的书，值得学习。
