We study and develop optical microscopes that help biologists and engineers address ... Our research interests include extending the depth of field of imaging systems, increasing image resolution ...

As the apertures only allow light from certain points of the sample to be detected, the sample (or the detector) must be scanned to create a full image. In the approach of Cui et al. this sample ...

Scanning near-field optical microscope (SNOM) – using the scattered light through a sub-wavelenght aperture to form an image. (Illustration by Kristian ... SNOM has revolutionized how scientists study ...
