Projects
This page highlights a selection of my ongoing and completed projects spanning experimental mechanics, elastic wave propagation, and optical system design. Alongside material testing and wave-based modeling, it features my Master’s thesis on SPIFI—a high-speed optical profilometer combining structured illumination and computational imaging.
Spatial Frequency Modulation for Imaging and Optical Profilometry
Objective & Motivation
-
To design and simulate a single pixel imaging (SPIFI) - based optical system capable of spatial frequency -encoded structured illumination for high speed profilometry.
-
To demonstrate imaging in both transmission and refection modes for transparent and metal samples.
-
Investigate the potential of this approach for fast, high-resolution, and cost-efficient surface characterization.
Approach
-
Modeled the complete optical layout in Zemax OpticStudio, including beam expansion, 4f relay, and cylindrical lens illumination.
-
Simulated beam propagation and diffraction from a spinning mask to study spatial frequency encoding.
-
Developed the preliminary theoretical framework linking spatial frequency modulation to surface profiling.
Current Status
-
Simulation results confirm correct frequency encoding behavior and provide baseline design tolerances.
-
Laying the groundwork for experimental validation and future depth measurement demonstrations.
