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：蜡，adiminstitution：Duke Universitytitle：急切：启用手机的光谱光学对比相干性断层扫描（OCT）系统已成为眼科医生的必不可少的视网膜成像工具，但它们的临床系统的成本最高为150,000美元，而临床系统的限制性限制了仅限制大型眼中的中心。如果有低成本的工具可用，则有很大的机会在护理点使用OCT。较低的成本将允许多种医生和验光师使用OCT技术。该项目中的技术和创新将使低成本的新型移动健康应用程序目前不可用。该急切建议的目的是基于通常用于手机中指纹扫描仪的线条扫描传感器创建低成本的高性能光谱仪。许多手机基于各种感测方法，都结合了指纹扫描仪。大多数指纹扫描仪都使用光学传感器，这是具有单线高像素计数传感器元件的光谱法的理想格式。在这个项目中，PI试图使用光学光谱法的光学指纹扫描仪来证明原理证明。所提出的光谱仪将是低成本（500美元），并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，它们将创建适用于光谱域光学相干断层扫描（SD-OCT）的光谱仪设计。
