光疗法是适用于各种疾病的治疗的新模式，其依赖于光学装置将光传输到目标组织。然而，大多数现有的设备都是由硬质材料制成的，并且通常与人体有一定距离。applied.at能够实现高平面光学性能的可磨损光波导仍然很少见到。本工作致力于开发一种新的设计方法，这种柔性波导，结合光散射点阵列和倒梯形透镜，以实现高的均匀性和效率，这是关键的性能标准。为了优化这些准则，建立了设计参数与性能之间的反向传播神经网络模型，并将其与粒子群算法相结合。此外，还通过仿真研究了散射点的深度、形状以及表面的透射和反射特性等对其它难以通过数值优化设计的元件性能的影响。通过简单易行的工艺技术，制作了优化的波导原型，并与光源组装在一起。在发射表面上的多个目标点上的测量的辐照度显示出与它们的模拟对应物的一致性，其中考虑了真实的原型与理想模型的一些不期望的失配。
Light therapies are new modalities of treatment applicable to various diseases, which rely on optical devices to.transmit light to target tissues. However, most existing devices are made of hard materials, and are usually applied.at a distance from human body. Wearable optical waveguides that can achieve high planar optical performance.are still barely seen. This work is devoted to developing a new design method of such flexible waveguides.incorporating arrays of light-scattering dots and inverted trapezoidal lenses to achieve high uniformity and efficiency,.which are the key performance criteria. To optimize these criteria, a backpropagation neural network.model between the design parameters and the performance is established, which is then incorporated with particle.swarm optimization. Furthermore, the effects on the performance of the other elements that are difficult to be.designed via numerical optimizations have been studied in simulations, such as the depth and shape of the scattering.dots and the transmitting and reflective character of the surfaces. Through easily accessible process techniques,.a prototype of the optimized waveguide has been fabricated, and assembled with a light source. The measured.irradiances on multiple target points on the emitting surface show the agreement with their simulated.counterparts, with some undesirable mismatches in the real prototype from the ideal model taken into account.
