针对特殊用途开发了一种新型掺Tb3+硅酸盐发光玻璃转换屏，可用于30 MeV的γ光子的成像探测；在低能X光(100 keV)作用下的空间分辨能力与301型发光玻璃相当，而在能量高达12 MeV的X光的照射下，其空间分辨能力不低于1.5 lp/mm，发光效率约为301型发光玻璃的3倍。

This thesis demonstrates the pre-polymers in a polymer-dispersed cholesteric liquid crystals can be polymerized into a polymer film, which can eliminate the aligning capability of the homogeneous alignment layer. Thereafter, the textures of the cholesteric liquid crystals in UV-cured region can be changed from reflective planar texture to the scattered focal conic one. Additionally, the clearing temperature of the liquid crystals can be reduced by doping with chiral dopant or monomers. The cause is the increase of the impurity concentration in LCs. In other words, if the monomers are polymerized, the clearing temperature of LCs in that region should increase due to the decrease of the impurity concentration. Therefore, impurities associated with doping with monomeric and chiral dopants cause the clearing temperature of LCs in cured region to differ from that in uncured region.

本文中，我们提出在高分子聚合物薄膜之胆固醇液晶(polymer-dispersed cholesteric liquid crystals，简称PDCLCs)中，利用紫外光使PDCLC中的单体聚合成薄膜，此即为光引致聚合反应，而该薄膜将原本在表面所作的配向膜覆盖且破坏其配向能力，使胆固醇液晶由原本反射的planar结构转换成散射的focal conic结构；另外，有关液晶材料的相变温度会由於掺杂手性分子或单体而降低，此因液晶材料内『杂质』浓度增加，而造成的液晶材料之不纯度增加，最终导致相变温度降低，若搭配上述光引致聚合反应，则由於光照区之单体聚合，使该区域单体占总材料之比例下降，即不纯度降低，进而使液晶材料之相变温度上升，该区域之相变温度与未照光区有所不同。

The assembly method of the invention has the main principles that a semiconductor laser, an optical coupled apparatus and a fiber head are orderly arranged, and the optical axes of the semiconductor laser, the optical coupled apparatus and the fiber head are arranged in a same straight line; the focal plane of an output beam which is focused on the fiber head is changed through utilizing and adjusting an adjusting device which can cause a beam to deviate; the sensitivity of the assembly adjustment of the adjusting device in the course of fixing is reduced.

本发明的方法的主要原理是将半导体激光器、光学耦合器件、光纤头依次排列，并使它们光轴在同一直线上，然后通过利用一使光束发生偏移的调节器件，通过调节该调节改变聚焦于光纤头的输出光束的焦平面，降低调节器件装配调节的固定时的敏感性。
