SU-8 exhibits interesting mechanical and optical properties for various MEMS applications, such as the development of micro lens and ball-like lens arrays. One of the most common method to fabricate such structures, is thermal reflow. However, a promising ...
In this thesis, we focus on the problem of recovering 3D shapes of deformable surfaces from a single camera. This problem is known to be ill-posed as for a given 2D input image there exist many 3D shapes that give visually identical projections. We present ...
We present an integrated beam steering system with a microlens scanner and a vertical cavity surface-emitting laser (VCSEL) source. The scanner and the VCSEL are assembled with an alignment sphere process and with an accuracy of 121 ±7 μm defined by precis ...
Adaptive optics is used to abate aberrations with a wavefront correction. It is widely used in astronomy and is starting to expand into applications of laser focusing and imaging with high numerical apertures, e.g. microscopy. The physical background of fo ...
Three approaches for visualization of transparent micro-objects from holographic data using phase-only SLMs are described. The objects are silicon micro-lenses captured in the near infrared by means of digital holographic microscopy and a simulated weakly ...
Laser scanning is commonly used in railways for detecting problems related with the clearance profile which are quite common especially in old tunnels. By increasing the resolution of the scanner system it is possible to use the images for identifying prob ...
This paper reports on the design, fabrication and optical characterization of a self-aligned microlaser scanning system consisting of a vertical cavity surface emitting laser (VCSEL) source and a MEMS-actuated microlens scanner. The alignment and the spaci ...
Selective laser sintering (SLS) and Selective Laser Melting (SLM) are parent layer manufacturing processes that allow generating complex 3D parts by consolidating layers of powder material on top of each other. Consolidation is obtained by processing the s ...
We report on the development of an opto-fluidic waveguide coupling mechanism for planar solar concentration. This mechanism is self-adaptive and light-responsive to efficiently maintain waveguide coupling and concentration independent of incoming light's d ...
Artists and architects often need to handle multiple constraints during design of physical constructions. We define a performative constraint as any constraint on design that is tied to the performance of the model--either during fabrication, construction, ...
