Biomolecules and nanostructures

The Optical Sciences group studies the interaction of light and matter at the nanoscale. We do this by exploring ways to shape light and its environment. It's what we call active and passive control. Our current focus is on the interaction of light with biomolecules and nanostructures. We are part of Twente University's Department of Science and Technology and member of the MESA+ institute.
We participate in the EU-COST actions MP1102: Coherent Raman microscopy (MicroCor) and CM1202: Supramolecular photocatalytic water splitting (PERSPECT-H2O)


Amplitude and phase information from imaging using a compound lens

collaboration with Allard Mosk of the COPS group, Univ. of Twente

  • Herman Offerhaus - Scientific Staff
  • Jeffrey Reuling - Former member

  • It has been shown in literature that a compound lens that consists of 4 sections can be used to extract phase information from an otherwise "conventional" microscopy image. We want to explore the requirements on the image (in terms of complexity and illumination bandwidth) and test a practical implementation of such a system.
