This thesis further explores the possibilities of scanning near-field optical microscopy (SNOM) in both materials and life sciences. Two experimental SNOM setups were developed: one designed for infrared spectroscopy applications and the other for the imag ...
From micro-assembly to biological observation, the optical microscope remains one of the most important tools for observing below the threshold of the naked human eye. However, in its conventional form, it suffers from a trade-off between resolution and fi ...
The atomic force microscope (AFM) is limited in imaging speed by the bandwidth and dynamic behavior of the actuators and mechanical parts. For high-speed imaging all AFM components have to be optimized in performance. Here, we present improvements of the f ...
We present an image-guided microscope system using augmented reality image overlays added onto one of the views of the operating microscope. With this system, segmented objects, outlines of risk regions or access pathways, previously extracted from preoper ...
In this thesis a new scanning near field optical microscope based on an apertureless scattering technique is introduced for resolving optical properties of surfaces with lateral resolution reaching 10 nm and better. The construction of the instrument is ba ...
In this letter, we describe the on-demand dispensing of single liquid droplets with volumes down to a few attoliters and submicrometric spacing. This dispensing is achieved using a standard atomic force microscope probe, with a 200 nm aperture at the tip a ...
The invention relates to an adjustable pinhole, especially for the illumination beam path and/or detection beam path of a laser scanning microscope. Said pinhole consists of at least two planar basic components comprising articulation points in the form of ...
Self-organized GaN/AlN stacked quantum dots (QDs) have been studied by means of cathodoluminescence (CL), near field scanning optical microscopy (NSOM), photoluminescence, mu-Raman, and transmission electron microscopy. Assignment of the optical emissions ...
In this thesis new imaging approaches for optical microscopy are proposed and studied. They are based on the use of dynamic structured illumination in combination with a demodulation detection concept employing CMOS image detectors. Two particular implemen ...
The advent of scanning near-field optical microscopy (SNOM) has augmented at a microscopic level the usefulness of optical spectroscopy in the region between 300 nm and 10 mum. Two-dimensional imaging of chemical constituents makes this a very attractive a ...
