This Small Business Innovation Research (SBIR) Phase I project will develop a Multiphoton Polymerization (MPP) fabrication technology to fabricate structures 100 times thicker than previously demonstrated for the technology to produce such structures. The research will focus on demonstrating that an MPP system with a 1-2 cm working distance of the fabrication optics in the depth direction can produce holes of 1 cm in length, with precisely controlled 8-10 micron diameter. Phase I will also determine whether the process can be scaled up sufficiently to fabricate the size of devices necessary - on the order of 1-10 cm per side section - requiring a multiplicity (10,000) of holes. Present configurations of MPP cannot provide the necessary working distance, nor is it apparent that there are any other technologies in existence that will work. Using "positive resist" Photo-Acid Generator (PAG) materials to form these structures, effectively "drilling" the holes, offers three potentially enabling technological advantages; lowering the optical dosage for polymerization, minimizing the material volume processed, and providing highly uniform hole dimensions that are controlled solely by adjusting the exposure and the power level of the laser. The potential benefits of the enhanced imaging enabled by this Retinal Image Management (RIM) technology will be in the fields of national defense/security for the USA, and vision health related applications.

该小型企业创新研究（SBIR）第一阶段项目将开发多光子聚合（MPP）制造技术，以制造比以前生产此类结构的技术厚100倍的结构。该研究将集中于证明，在深度方向上具有1-2 cm加工光学器件工作距离的MPP系统可以产生长度为1 cm的孔，具有精确控制的8-10微米直径。 第一阶段还将确定该工艺是否可以按比例放大到足以制造所需的设备尺寸-每个侧面1-10厘米的数量级-需要多个（10，000个）孔。 MPP的当前配置不能提供必要的工作距离，也不明显存在将工作的任何其他技术。 使用“正性抗蚀剂”光酸发生剂（PAG）材料来形成这些结构，有效地“钻”孔，提供了三个潜在的使能技术优点：降低用于聚合的光剂量，最小化处理的材料体积，以及提供仅通过调节曝光和激光功率水平来控制的高度均匀的孔尺寸。这种视网膜图像管理（RIM）技术所实现的增强成像的潜在好处将在美国国防/安全领域以及与视力健康相关的应用领域。
