Researcher Biography

I am Jingyu Wang, from Tianjin, China. I have a background of Biomedical Engineering and my interests are focused on imaging technology.

Project Outline

My project is funded by HIRESOMI, Marie Curie EST Network. For the moment, I am working on a Full-field OCT system. I am trying to explore the applications of OCT imaging and measurement with the help of a high-sensitivity CCD camera (Andor DV887). So far, low N.A optics was used in Full-field OCT to build a Coherence Radar which can measure the topology of object surface by phase-shifting method. By introducing multiple-delay-lines into the interferometer, the contour information of a curved object surface can be obtained from a single en-face OCT image. This could be used in the measurement of the cornea curvature. With high N.A. optics, a Linnik interferometer is built. This high N.A set-up will enable high transverse resolution.

I also have the intention to replace the SLD with a large bandwidth source to obtain better depth resolution. Besides, I am planning to construct a Spectral Domain Line scanning OCT employing the same high-sensitivity CCD camera.
