Electron crystallography determines the structure of membrane proteins and other periodic samples by recording either images or diffraction patterns. Computer processing of recorded images requires the determination of the reciprocal lattice parameters in ...
In this paper, we will report our recent development of a new type of OptoFluidic Microscope (OFM) that is capable of delivering resolution beyond the diffraction limit of light. Accurate control of the sample translation is accomplished by adopting an opt ...
In this paper, Digital Holographic Microscopy (DHM) is presented as a powerful tool for quality control of micro-optical components. It will be shown that not only the single-shot full field-of-view nanometer axial resolution makes DHM an ideal solution fo ...
Nowadays, the use of micro- or nano-patterned surfaces is well established in wide fields of science and in numerous applications in the industry. Periodic surface-relief profiles with dimensions in the wavelength range of the light can act as diffractive ...

In optics, optical elements are used to transform, to filter or to process physical wavefronts in order to magnify images, compensate for aberration or to suppress unwanted diffracted order for example. Because digital holography provides numerical wavefro ...
Biomimetic apatite coatings were obtained by soaking chemically treated titanium in SBF with different HCO3- concentration. XRD, FTIR and Raman analyses were used to characterize phase composition and degree of carbonate substitution. The microstructure, e ...
An uncooled thermal detector array with low NETD is designed and fabricated using MEMS bimaterial structures. A diffraction grating is embedded on the pixel membrane for sensing sub-nm mechanical deflections. The first order reflected light was focused on ...

We present a photonic meta-material with planar dielectric chiral structures on SU-8 realized using nanoimprint lithography (NIL). A Si template with chiral structure arrays was first fabricated by electron beam lithography (EBL) followed by reactive ion e ...
Performance monitoring is one of the key features to create self-managed optical networks. Monitoring the characteristics of an optical channel is important for designing robust and reliable optical telecommunication system. This thesis examined the use of ...
The field of photonic crystals is a rapidly developing branch of modern optics. Photonic crystals are believed to be the cornerstone for a wide range of new photonic devices controlling the confinement and propagation of light. These artificial structures ...
