项目摘要

DESCRIPTION (provided by applicant): SBIR project aims to develop a novel compact, large stroke, low-cost Silicon MicroMembrane Deformable Mirror (SiMM DM) system to be used in ocular Adaptive Optics (AO) for improving the resolution of retinal imaging. Given its superior performance, high reliability, low cost, and compactness, the DM system holds the promise of enabling true commercialization for AO technology into conventional ophthalmic instruments including fundus camera, confocal Scanning Laser Ophthalmoscope (SLO) and Optical Coherence Tomography (OCT) systems and to be widely used in biomedical microscopes and laboratory tools for eye research. PUBLIC HEALTH RELEVANCE: In order to maximize spatial resolution to a micro scale of single retinal cells and to improve visual performance of the eye to supervision, correction of the ocular aberrations to make the eye free of aberration is necessary. The project aims to develop a novel large pixel-stroke (up to 50- 5m) deformable mirror capable of achieving up to 99% correction in clinical population.

描述（由申请人提供）：SBIR项目旨在开发一种新型的紧凑，大中风，低成本的硅微膜可变形镜（SIMM DM）系统，用于在眼部自适应光学（AO）中用于改善视网膜成像的分辨率。鉴于DM系统具有出色的性能，高可靠性，低成本和紧凑性，因此具有将AO技术的真正商业化的承诺投入到传统的眼科仪器中，包括眼底摄像头，共聚焦扫描激光眼镜（SLO）（SLO）（SLO）和光学相干性层造影（OCT）系统（OCT）系统，并在生物学微型范围内广泛使用。公共卫生相关性：为了使单个视网膜细胞的微观尺度最大化空间分辨率，并提高眼睛的视觉性能对监督的视觉性能，需要校正眼像畸变以使眼睛无像差。该项目旨在开发一种新型的大型像素冲程（高达50-5m）的可变形镜，能够在临床人群中获得多达99％的校正。
