Proposal: 1445992PI: Wax, AdamInstitution: Duke UniversityTitle: EAGER: Cell phone enabled spectroscopyOptical Coherence Tomography (OCT) systems have become an essential retinal imaging tool for ophthalmologists but their cost of up to $150,000 for clinical systems has restricted access to only large eye centers. There is significant opportunity for using OCT at the point of care, if a low cost instrument were available. The lower cost will permit use of OCT technology by a wider range of physicians and optometrists. The technology and innovation in this project will enable low cost novel mobile health applications currently unavailable.The goal of this EAGER proposal is to create a low cost, high performance spectrometer based on line scan sensors typically used for fingerprint scanners in cell phones. Many cell phones incorporate fingerprint scanners based on a variety of sensing methods. Most fingerprint scanners use an optical sensor, which are an ideal format for spectroscopy with single line high pixel count sensor elements. In this project the PI seeks to demonstrate proof of principle using an optical fingerprint scanner for high performance spectroscopy. The proposed spectrometer will be low cost ($500) and enable high resolution spectroscopy as well as fast signal acquisition. To demonstrate the utility of the proposed platform, they will create a spectrometer design suitable for spectral domain optical coherence tomography (SD-OCT).

提案：1445992PI：Wax，Adam 机构：杜克大学 标题：EAGER：手机支持的光谱光学相干断层扫描 (OCT) 系统已成为眼科医生必不可少的视网膜成像工具，但其高达 150,000 美元的临床系统成本限制了只能进入大型眼科中心。如果有低成本仪器，则在护理点使用 OCT 的机会很大。较低的成本将使更多的医生和验光师能够使用 OCT 技术。该项目的技术和创新将实现目前无法实现的低成本新型移动健康应用。该 EAGER 提案的目标是基于通常用于手机指纹扫描仪的线扫描传感器创建低成本、高性能的光谱仪。许多手机都配备了基于各种传感方法的指纹扫描仪。大多数指纹扫描仪都使用光学传感器，这是采用单线高像素数传感器元件进行光谱分析的理想格式。在这个项目中，PI 试图展示使用光学指纹扫描仪实现高性能光谱的原理证明。所提议的光谱仪成本较低（500 美元），可实现高分辨率光谱以及快速信号采集。为了展示所提出的平台的实用性，他们将创建适合谱域光学相干断层扫描（SD-OCT）的光谱仪设计。
