Paper Abstract

The art of optical motion capture combines computational devices with optical detectors. The spatial and temporal resolutions desired require millions of discrete detection locations, or pixels, operating at frame rates ranging from several hertz to several thousand hertz. Processing frames from multiple detectors in real time, requires several billion operations to be performed per second. The process expands as the frame rate or resolution increases. One technique suggested here is utilization of orthogonal one dimensional (1-D) CCD or linear array detectors, instead of the more common two dimensional (2-D) CCD or area array detectors. A brief description of the advantages of the linear arrays is provided based on experience with an actual system, validating empirical supposition with proven results. Extrapolations into future developments are suggested, combining the best of both designs.
