Results: The refraction results of the Allegretto Wave Analyzer were very unstable. The spherical, cylinder diopter and the axis of the cylinder varied greatly. The refractive errors were large while the refractive errors were little by the subjective refraction examinations. During the wavefront examination, spots of the laser matrix were blurring, and the reproducibility was not good. Wavefront analyses showed that the Array pseudophakic eyes had relative large coma while the patients had no obvious symptoms.

研究结果：像差分析仪检测得的屈光度结果十分不稳定，球镜度、柱镜度、散光轴都变化很大，可重复性差，检测的屈光不正度数较大，而主觉验光时，患眼的屈光不正度数较低。5只眼的光学矩阵的测量点均非常模糊，且测量结果的可重复性较差，像差分析显示，Array人工晶状体有很大的第三阶彗差，但患者的自我感觉良好。

本实验使用纹理分析的方法研究正常膀胱壁组织和膀胱赘生物组织的纹理特征，并筛选出四种存在显著统计学差异的纹理特征，为后续利用纹理特征研究膀胱肿瘤浸润肌层深度提供了依据。另外，如前所述，目前膀胱肿瘤的诊断主要依靠膀胱镜，但作为一种侵入性操作，膀胱镜并不适合人群疾病普查和患者的治疗后随访。

The research which is the important part of the tunable erbium-doped fiber laser is composed of two main parts: 1. the gain part of the tunable erbium-doped fiber laser, which in fact is an erbium-doped fiber amplifier, its output characteristics are discussed both in theory and experiment, and the differences are also discussed between theory and experiment; 2. the saturated absorber part of the tunable erbium-doped fiber laser, also the part to narrow the line width of the fiber laser. The line-width narrowing mechanism in fiber laser induced by unpumped Er-doped fiber is presented from the aspect of coupling wave equation, and the main factor is considered as the standing wave induced by interference. The line-width is narrower when the standing wave is stronger, and the narrowing effect disappears with the disappearance of the standing wave. In the experiment, when adding a Faraday mirror in the laser cavity to remove the standing wave , the narrowing effect disappears. So the theory is proved by the result of the experiment.

本课题的研究内容是集成光学声光可调谐掺铒光纤激光器的重要组成部分，主要分两部分：1、声光可调谐掺铒光纤激光器中增益部分的研究，相当于对掺铒光纤放大器的研究，理论上对掺铒光纤放大器的输出特性进行分析，实验上实现了掺铒光纤放大器系统，并将实验数据与理论计算数据进行对比，分析了误差产生原因；2、声光可调谐掺铒光纤激光器中饱和吸收体部分的研究，即压窄光纤激光器输出线宽的研究，从耦合波方程出发，理论上解释了未泵浦掺铒光纤压窄光纤激光器线宽的原理，分析了影响该作用的主要因素是未泵浦掺铒光纤中相对传输的光干涉形成的驻波：驻波越强，压窄效果越好，相反当没有驻波时，没有压窄效果，在实验上通过在激光器腔内加入法拉第旋转镜使驻波消失，同时压窄效果消失，从而验证了理论分析的正确性。

In chapter 3, characteristic paraments, focusing structure were discussed, the processing of double cell for phase conjugation was analyzed. Designing criteria of double cell phase conjugation mirror was given out. All phase aberrations could be compensated by using phase conjugation theoretically, but compensation is only effective to phase aberration of uniform polarizing state, it is not effective to aberration by thermally induced depolarization an diffractive effecting by aperture.

在第三章，我们讨论了SBS介质的特性参数，相位共轭镜的聚焦结构，分析了双池相位共轭镜的相互作用过程，给出了相位共轭镜的设计原则；从理论上讲相位共轭技术可以完全补偿热畸变以及因各种光学不均匀性造成的光束畸变，但是相位共轭技术只对偏振态均匀的相位畸变造成的光束畸变起补偿作用，而对由于热致双折射效应造成的退偏以及光束通过硬边光阑时的衍射效应造成的光束畸变无能为力。
