Five-Axis Goniometric Stage

Abstract:

Five-axis goniometric stages have been used in laser eye safety research for over forty years. The stages are able to translate in three dimensions and rotate about either eye of a prone-placed subject. This report describes the design, implementation, and operation of a five-axis goniometric stage. The latest design incorporates many ideas from previous versions while adding reliability and functionality improvements, such as a position indicator option. Most notably, the current design merges the rotary and linear portions into a single contained motion system. A manual control box facilitates the operation of the two rotational axes and three linear travel axes. The design criteria for the goniometric portion of the stage nominally called for - 15 degrees pitch adjustment and 1 40 degrees of rotational adjustment. The XY section was designed for 6.5 inches 16.5 cm of travel in each axis. The height stage section was required to have 8 inches of range with a center of motion approximately 46 inches above the floor.
