Transfer characteristics of white light interferometers and confocal microscopes
(2017-11-23)
Optical profilers present significant advantages in comparison with stylus profilometry and scanning probe microscopy due to their non-contacting technique and their ability to scan the entire measurement field simultaneously. However, optical profilers suffer from different systematical artifacts. The dissertation investigates the transfer characteristics of optical profilometers, namely white light interferometers and confocal microscopes.
In white light interferometry dispersion in the optical system leads to ...

Optical Sensor Array based Nanospectrometer: Fabrication of high resolution 3D NanoImprint master templates and bonding of Fabry-Pérot filter array onto photodetector array
(2017-05-11)
In the field of optical spectroscopy, spectrometers are high resolution optical sensors that have emerged as a platform for a wide range of application fields. Commercially available spectrometers are bulky and expensive. Hence, this limits its integration into modern mobile and wearable devices. To overcome this limitation, miniaturization of spectrometers is an interesting target for a wide range of emerging applications. The most attractive concept of fabricating miniaturized spectrometers is the Fabry-Pérot filter ...
