About me

I am a PhD candidate at the Delft Center for Systems and Control of the Delft University of Technology with the supervision of Prof. dr. ir. Michel Verhaegen and Prof. dr. Gleb Vdovin . Currently, I am working on the lensless imaging methods by making use of wavefront sensing techniques from adaptive optics. Other novel phase imaging approaches such as digital micromirror device (DMD) based phase retrieval are under development as well. With me, you can build a more sophisticated quantitative phase contrast imaging microscope for imaging the invisible specimen in the Smart Optics Lab. This project usually involves hands-on optical experiments, wavefront sensing technologies and computational imaging.

Profile

Research

Lensless coherent imaging based on digital micromirror device

The coherent complex optical field can be registered by a digital micromirror device (DMD) with a sequence of sampling masks. The phase is retrieved from the far field interferograms or diffraction patterns.

Phase imaging with a Shack-Hartmann wavefront sensor

The Shack-Hartmann wavefront sensor (SHWFS) is maturely developed in the field of adaptive optics. With the increase of its spatial resolution, the SHWFS provides a simple solution for quantitative phase imaging and holographic imaging with the properties of referenceless, realtime acqusition and robust measurement.

Tunable external cavity diode laser

This project was developing a wide mode-hop free range tunable diode laser which is applicable for frequency-swept absolute distance measurement in airplane assembling and high precision machine tools.
