摘要： A method of hot rolling or extrusion of a textured-surface sheet can be used to produce a large one dimensional array of fibers; these arrays can be stacked to form the two dimensional matrix required for image transfer. Alternatively, a flat ribbon can be rolled or extruded and the fiber array formed from it by altering the refractive index of alternate strips using diffusion ion exchange or implantation methods.

摘要： Fine-grained polygonized halide alloy bodies are formed having comparable optical properties to a single crystal halide body. Heat and force are applied to a single crystal halide to recrystallize or polygonize the halide. Room temperature grain growth observed in fine-grained pure halides is inhibited by alloying.

摘要： A nondestructive dynamic controller for thermoplastic development is disclosed. The dynamic controller monitors the development of a hologram, without altering the charge pattern on the recording medium that is required for the development. The dynamic controller determines when optimum deformation has occurred in the developing recording medium and provides a signal which is used to shut off the thermal input used in the development.

摘要： Optical waveguides are fabricated by heating a region of a body of flat filter glass with an energy beam such as a scanning focused laser beam. The region is locally heated to a temperature at which softening occurs. Upon cooling two differing effects occur, the two effects causing a "W" shaped index of refraction profile. The first effect is the photoelastic effect due to the residual stress introduced as the heated material cools and contracts. The residual tensile stress is constant in the softened region, but decreases as the distance from the center of the heating increases. Since the density and therefore the refractive index of this region is inversely proportional to the residual stress, this effect resulted in a local refractive index minimum. The other effect is the material density change in the softened region. As the cooling rate is small in the center and large in the edge of this softened region, a density change occurs with the center attaining the highest value and decrease towards the edge. The refractive index change due to this effect is proportional to the density and therefore resulted in a peak. The combined result of these two effects produces a "W" shape refractive index profile.

摘要翻译： 通过用诸如扫描聚焦激光束的能量束加热扁平滤光器玻璃体的区域来制造光波导。 该区域被局部加热到软化发生的温度。 冷却时，会发生两种不同的影响，这两种效应造成“W”形折射率折射率分布。 第一个效果是由于当加热材料冷却和收缩时引入的残余应力引起的光弹效应。 残余拉伸应力在软化区域是恒定的，但随着加热中心的距离增加而减小。 由于该区域的密度和因此的折射率与残余应力成反比，所以该效应导致局部折射率最小。 另一个效果是软化区域的材料密度变化。 随着中心的冷却速度小，软化区域的边缘较大，随着中心达到最高值并向边缘减小，发生密度变化。 由于这种效应导致的折射率变化与密度成比例，因此导致峰值。 这两种效应的组合结果产生“W”形折射率分布。

摘要： Optical waveguides are fabricated by heating a region of a body of optical material with an energy beam. The region is locally heated to a temperature at which plastic deformation occurs as a result of the constraints placed by the unheated adjacent material. The plastic strain produced at high temperature translates into a residual stress as the material cools which results in a greater index of refraction within the region than in surrounding regions.
