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 concept patented by Dr. Andrew Dainis. The terms of the CRADA state that the NIH may develop a clinical operating 3-D motion analysis system using the concept; in return, the NIH may keep the system. Dr. Dainis will have rights to BEIP's refinements. 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 Dr. Dainis's patent is that each camera has 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 NIH 的临床医生和研究人员可以使用人体运动。 这 BEIP 升级了 Dr. Stanhope 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。 此次升级解决了很多问题 原Vicon系统的问题，但快速运动分析仍然存在 受到系统每秒 25 帧的慢帧速率的限制。 这 生物力学实验室需要一个系统以每帧 2000 帧的速度获取数据 第二。 为了满足这一要求，斯坦霍普博士要求 BEIP 开发了三维运动测量系统，使用 安德鲁·戴尼斯 (Andrew Dainis) 博士的概念已获得专利。 CRADA 的条款规定 NIH 可能会开发一种临床操作 3D 运动分析系统，使用 概念；作为回报，NIH 可以保留该系统。 戴尼斯博士将 有权对 BEIP 进行改进。 在这次与生物力学的合作中 BEIP 实验室和 Dainis 博士将开发、制造和测试 系统电子学。 Dainis 博士将开发 CCD 的光学器件 线性阵列和系统软件。 Dainis博士的专利理念 是每个相机有四个线性CCD阵列，每个阵列有 专门设计的镜头。 阵列被放置在表面上 相机以特殊模式转换来自目标的光源 进入其空间坐标。
