DESCRIPTION (provided by applicant): Millions of people in the USA and throughout the world are affected by neurological disorders such as epilepsy, Parkinson's disease and brain tumors. Confocal microscopy has considerably enhanced the testing of hypotheses in the basic neurosciences, providing significant insights into the causes of such neurological disorders. However, these systems are currently extremely expensive, putting them out of the reach of most individual scientists; the majority of confocal microscopes are currently to be found only in core facilities. There is also a need for increased optical resolution and the ability to perform 3-dimensional reconstructions of samples using a confocal microscope. If a system could be brought to market at a cost of less than $50,000, confocal microscopy would become available to every individual scientist using fluorescence microscopy, thus improving research abilities and potentially alleviating the financial and medical burdens caused by neurological disorders. The overall goal of this project is to develop a new type of confocal microscope based on an innovative concept - the swept-field confocal design (SFC). The SFC is a revolutionary confocal concept. This hybrid-instrument uses an array of stationary pinholes for illumination and detection along one axis while using a single galvanometer to sweep the illumination along the other axis (Patent Pending). In Phase I of this project we designed, built prototypes of and evaluated the performance of two variations of the SFC. In Phase II of this project we will move from the drawing board to the laboratory; we will develop, test and refine a high-performance, easy-to-use swept-field confocal microscope at a selling price of under $50,000.

描述(申请人提供)：在美国和世界各地，数以百万计的人受到癫痫、帕金森氏症和脑瘤等神经系统疾病的影响。共聚焦显微镜极大地加强了对基础神经科学中假说的检验，为此类神经疾病的原因提供了重要的见解。然而，这些系统目前极其昂贵，使它们超出了大多数科学家个人的承受能力；目前大多数共焦显微镜只能在核心设施中找到。还需要提高光学分辨率和使用共聚焦显微镜对样品进行三维重建的能力。如果一个系统能够以不到5万美元的成本推向市场，共焦显微镜将为每一位使用荧光显微镜的科学家提供服务，从而提高研究能力，并有可能减轻神经疾病造成的经济和医疗负担。 本项目的总体目标是基于一种创新的概念--扫场共焦设计(SFC)来开发一种新型的共焦显微镜。证监会是一个革命性的共焦概念。这种混合仪器使用一组固定的针孔沿一个轴进行照明和检测，同时使用一个检流计沿另一个轴扫描照明(专利正在申请中)。在这个项目的第一阶段，我们设计、建造了SFC的两个版本的原型，并评估了它们的性能。在这个项目的第二阶段，我们将从绘图板转移到实验室；我们将开发、测试和改进一种高性能、易于使用的扫描场共焦显微镜，售价低于50,000美元。
