Research Interests
Advancing the fundamental principles and applications of micro-optics and biophotonics systems.
Optical Coherence Tomography (OCT)
Our group focuses on signal processing optimization and microstructural imaging using Spectral Domain OCT (SD-OCT). We develop innovative methods utilizing Wigner-Ville techniques and signal distributions to enhance spatial resolution thresholds. Our applied fields span across non-destructive post-harvest agricultural testing and advanced biophotonics diagnostics.
- SD-OCT Signal Processing
- Wigner-Ville Distribution
- Agricultural Sub-peel Imaging
- High-Resolution A-Scans
Diffractive Optics
We specialize in the design, numerical simulation, and fabrication of advanced diffractive optical elements (DOEs). This research involves beam shaping setups, structural illumination profiles, and engineering sidelobe-suppressed modified Bessel beams. These custom optics components directly drive breakthroughs in light-sheet microscopy platforms.
- Beam Shaping Optic Design
- Modified Bessel Beams
- Light-Sheet Microscopy
- Diffractive Element Masking
Metaoptics
Our metaoptics vertical explores flat, ultra-compact dielectric metasurfaces engineered using sub-wavelength Silicon Nitride structures. We leverage electron-beam lithography (EBL) techniques to fabricate planar elements tailored for aberration corrections in highly portable medical devices, such as scanning fiber fluorescence microendoscopes.
