Nanostructured gradient index microoptics
2015 17th International Conference on Transparent Optical Networks (ICTON), 2015Nanostructured gradient index (nGRIN) elements are a new class of planar-surface micro-optical components which transform optical wavefront by discrete, subwavelength changes in the refractive index perpendicular to the optical axis. We have developed a series of various nanostructured micro-optical components with various functionalities using ...

Journal of Microelectromechanical Systems, 2008
A new class of tunable and actuated microoptical devices is presented: pneumatic microoptics. Using microelectromechanical system fabrication technology extended by the use of polydimethylsiloxane (PDMS) membranes, tunable microlenses, and lens arrays, actuated micromirrors with large tilt angles and tip-tilt piston mirrors have been designed and ...

Computational optics and microoptics - a mutual benefit
Imaging and Applied Optics 2019 (COSI, IS, MATH, pcAOP), 2019Microoptics offers novel and compact implementations for imaging and sensing, however, usually with a reduced space-bandwidth product (resolution). Computational techniques can compensate for this drawback and yield high quality performance.

SPIE Proceedings, 2006
Rotational prisms or reflectors are used for conventional optical scanners. Their disadvantages are large size, low scanning speed and high power consumption. In the paper a microoptical scanner based on the integration of piezoelectrical driver and microlens arrays is described.

Construction kit for microoptical systems on the basis of microoptical benches
Symposium on Design, Test, Integration and Packaging of MEMS/MOEMS 2003., 2004Manufacturing test structures of microsensors and microactuators is very expensive in terms of time and materials. In a conventional design process, this limits the number of design variants to be considered. For this reason, computer-supported design techniques are gaining importance in microsystems technologies.
