For near-field optical systems, Aperture and Solid Immersion Lens that are popular techniques can overcome light diffraction limit and reduce spot size.

奈米孔与固态浸没透镜是在近场光学系统中，常用来克服绕射极限和缩小光记录点的两项技术。

Using Solid Immersion Lens is another method to realize near-field optical data storage. Here with a basic optical system of SIL, a static SIL optical storage system is built up, and a result of ~450nm recording track is obtained on CD-RW disc.

Next, we reviewed the connection between RBLs and XBLs and the energy radiative process of BL Lacertae. Synchrotron radiation from radio to optical band and inverse Compton Scattering in γ ray wavebands are a wide accepted point. The beam model and gravitationally lensed model are two models associated with the radiative process. At present people tends to favor the previous one.

接着我们对射电选BL Lac型天体和X射线选BL Lac型天体之间的关系以及BL Lac型天体的能量辐射机制进行了评述，从射电到光学的同步辐射和γ射线波段逆康普顿散射的观点受到大家的普遍接受，射束模型和引力透镜模型是与辐射机制相关的两种模型，目前比较倾向于射束模型的解释。

This method also allow us to select the most efficient way from the bulk optical systems and available recoding methods, i.e., identifying the space bandwidth product of the input signal, the minimum size of lens apertures, the sample space and total sample number of CCD and spatial light modulator, the need of magnification before the signal passes through a SLM or when the signal reaches the camera.

通过该方法可以确定合适的加密系统和光学器件，例如输入信号的空间带宽积、变换透镜的最小孔径、空间光调制器的分辨率和像素大小、CCD的分辨率和像素大小以及入射到空间光调制器和CCD靶面上光场所需的放大倍数。

The simulation result shows the collection efficiency of TIR lens model is 67% when the angle of light is confined within 15°. And the uniformity on observation screen is improved in some degree. The optimal design of TIR lens further provides the development space of LED micro-projection display system.4 On the base of the theory research and the model simulation, four projection display systems which have LCOS as micro-display panel and which combine different optical devise for UHP and LED light source respectively are proposed in this dissertation. And the quality of projection display system is evaluated by thesimulation outcome.

模拟结果表明，优化后的TIR透镜可实现将LED大角度扩展光束中67％的光能压缩到15°范围以内，并使目标屏的照明均匀性得到一定的改善，这为LED光源微投影显示系统设计提供了新的发展空间。4在以上理论研究和模拟分析的基础上，将优化和改造得到的照明光学元件应用到微投影显示的照明系统设计中，分别采用UHP和LED光源，设计了四套单片式LCOS微投影显示系统模型，通过光线追迹模拟结果，对系统性能进行了评价分析和对比。
