What is Design and Construction of a Fine Drive System for Scanning Optical Elements about?
The design and operation of a simple mechanical drive system, which is able to perform a fine course of angular motion, are reported. The system consists of a lead screw, a drive nut, sine bar legs, and an output shaft that can scan the optical holder mount. With a stepper motor coupled to the lead screw and interfaced to a PC, it is possible to control the scanning operation. When a 800 step/turn motor is used, it is possible to have an angular resolution of about 0.5 mdegree for a dynamic range of about 231. The reproducibility of the results is about 0.22% for the scan angle and the hysteresis effect of the system is in the range of 1.71%. For a total scan of 51,200 steps, a scan angle of about 23.31 is acheived. The fitted line to the experimental results shows that scan angle changes linearly with the scan length. With good precision in system construction and careful alignment, the overall nonlinearity can be less than 1%.
