The Biomechanics Laboratory makes quantitative information concerning human motion available to clinicians and researchers at the NIH. The BEIP has upgraded Dr. Stanhope's Vicon Motion and Image Analysis System by designing and fabricating six video-camera units, each with a variable intensity dual-wavelength infrared strobe. The upgrade solved many of the original Vicon system's problems, but fast motion analysis is still limited by the system's slow frame rate of 25 frames per second. The Biomechanics Laboratory requires a system to take data at 2000 frames per second. To satisfy this requirement, Dr. Stanhope requested that the BEIP develop a three-dimensional motion measurement system, using a novel idea patented by Dr. Andrew Dainis. The terms of the CRADA state that the NIH will develop a clinical operating 3-D motion analysis system; in return, the NIH will keep the system. Dr. Dainis will have all rights to the BEIP's part of the design. In this venture with the Biomechanics Laboratory and Dr. Dainis, the BEIP will develop, fabricate, and test the system electronics. Dr. Dainis will develop the optics for the CCD linear arrays and the system software. The idea of the patent is that each camera will have four linear CCD arrays, with each array having a specially designed lens. The arrays are placed on the face of the camera in a special pattern to translate a light source from a target into its spatial coordinates.

生物力学实验室提供有关以下方面的定量信息 美国国立卫生研究院的临床医生和研究人员可以使用人体运动。这个 BEIP升级了Dr.Stanope的VICON运动和图像分析系统 通过设计和制造六个摄像机单元，每个单元都有一个变量 强度双波长红外频闪。此次升级解决了许多 原来的维康系统的问题，但快速运动分析仍然是 受到系统每秒25帧的缓慢帧速率的限制。这个 生物力学实验室要求系统以每秒2000帧的速度采集数据 第二。为了满足这一要求，斯坦霍普博士要求 BEIP开发了一种三维运动测量系统，使用一种新型的 这个想法由安德鲁·戴尼斯博士申请专利。CRADA的条款规定 美国国立卫生研究院将开发一种临床操作三维运动分析系统； 回来，美国国立卫生研究院将保留该系统。戴尼斯博士将拥有所有权利 BEIP是设计中的一部分。在这场与生物力学的冒险中 实验室和Dainis博士，BEIP将开发、制造和测试 系统电子学。戴尼斯博士将为电荷耦合器件开发光学元件 线阵和系统软件。这项专利的想法是 每个摄像头将有四个线阵CCD，每个阵列有一个 特别设计的镜头。阵列被放置在相机的表面上 以一种特殊图案将光源从目标转换到其 空间坐标。
