PLANO DE ESTÁGIO
Much of modern day technology is fabricated with high precision tools, requiring quick and accurate positioning at the micrometer level. Similarly, much experimental scientific work requires not only positioning at the micron level, but also diagnostics capable of tracking positioning errors and correcting them.
The objective of this work is to integrate a mechatronics (mechanical + electronic) platform that allows computer controlled sub-micron positioning, as well as characterise it using interferometric optical methods. The project comprises the following stages:
1. Using stepper motors, encoded DC motors and linear actuators, design and implement a suitable mechanical stage configuration for accurate linear motion with micronresolution over centimeters of range. Design suggestions will be given as the starting point of this work.
2. Implement the computer interface using standard control electronics, including control and test software.
3. Quantify the performance of the stage using interferometric techniques - by using a Michelson interferometer one can measure sub-wavelength displacements and quantify the performance of the stage across its full range. Similarly, means to quantify interface control stage response time will be devised (i.e. how fast can one move the stage to different positions).
4. As a proof of concept of the technology, by using 2 of such positioners and a tightly focused femtosecond laser, one can demonstrate a prototype laser marker. Marking tests at different speeds and fluences will be done, by proper stage control. Vector-based and pixel-by-pixel marking pattern performance should be analyzed.
