EAGER: Cell phone enabled spectroscopy

提案：1445992 PI：Wax，AdamInstitution：杜克大学EAGER：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，但其临床系统高达15万美元的成本限制了只有大型眼科中心才能使用。如果有低成本的仪器，在护理点使用OCT的机会很大。较低的成本将允许更广泛的医生和验光师使用OCT技术。该项目的技术和创新将使低成本的新颖的移动的健康应用程序目前unavailable. EAGER建议的目标是创建一个低成本，高性能的光谱仪线扫描传感器的基础上，通常用于手机中的指纹扫描仪。许多手机结合了基于各种感测方法的指纹扫描仪。大多数指纹扫描仪使用光学传感器，这是具有单线高像素数传感器元件的光谱学的理想格式。在这个项目中，PI试图证明使用光学指纹扫描仪进行高性能光谱分析的原理。拟议的光谱仪将是低成本（500美元），并使高分辨率光谱以及快速信号采集。为了证明所提出的平台的实用性，他们将创建一个适用于谱域光学相干断层扫描（SD-OCT）的光谱仪设计。

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).
