Piezoelectric Flexure-Based Micro-Mirror

I designed a flexure-based micro-mirror system using titanium alloy with a silicon reflective surface to achieve a single translational degree of freedom (DOF). The design leverages a piezoelectric actuator to optimize the mirror's natural frequency, suppressing unwanted motions while maintaining precise control and high-speed operation.

Drawing on advanced engineering techniques, I used twist-wrench mass and stiffness matrices to synthesize the design and validated performance through Finite Element Analysis (FEA). The project emphasized thermal stability, minimized parasitic error, and fabrication feasibility, with components theoretically manufactured using CNC milling and photolithography processes.

Designing a flexure-based micro-mirror system refined my expertise in precision engineering, material science, and advanced fabrication methods. This experience deepened my understanding of engineering's iterative and innovative process.
