Abstract
This work describes the design of an optomechatronics system controlled with LabVIEW via RS232 serial port. The system, that uses polarized light from a He-Ne laser, is applied in an optical sensing technique by Surface Plasmon Resonance (SPR) in the prism-based Kretschmann configuration, for optical characterization of thin film and biosensing applications. Since the measurements must be of high accuracy and insulated from mechanical noise, optomechatronics system improvements are realized by integrating control of Stepper Motor Rotary Stages that accomplish the required system features. The results showed that the system can yield reliable measurement data and greater precision.
