This paper examines the characteristics of a new laser-based optical position sensing technique that has been under development in the Department of Mechanical Engineering at Kansas State University. Previous investigations with the technique focused on quasi-static single degree of freedom position measurements using a single laser-generated light sheet. The present paper extends the basic concept by utilizing two intersecting laser light sheets to sense spatial position in two dimensions. The image of the intersecting light sheets is viewed on a flat reflective screen. It is detected by a high resolution video camera, with associated frame grabbing hardware/software, and subsequently related to body position by processing the video image of the intersecting light sheets.
