Detailed Study of Laser Diode Array Collimation based on Tolerancing Analysis Open
This work investigates how misalignments of collimation lenses affect two performance criteria: minimum throughput within an angular window and maximum beam height. Based on these criteria, we establish an alignment concept for the first s…
MEMS-scanning-based image projection simulation Open
The absence of simulation tools to predict image quality significantly complicates the hardware and software development of MEMS scanning-based projection systems. In this work, we present a mathematical and simulational framework to accur…
Modelling of Evanescent Field Scattering Open
Evanescent field particle scattering is a promising method for single particle detection. In this study, we performed a detailed numerical analysis to show the possibilities and limitations of analytical models for predicting the capabilit…
Integrated evanescent field detector for ultrafine particles—theory and concept Open
Recent studies on ultrafine particles (UFP), which are smaller than 100 nm, emphasized their hazardous potential to the human organism. They are comparable in size to typical nano-organisms such as viruses and can penetrate physiological b…
Fog Effects on Time-of-Flight Imaging Investigated by Ray-Tracing Simulations Open
Time-of-Flight (ToF) sensors are a key technology for autonomous vehicles and autonomous mobile robotics. Quantifying the extent of perturbation induced by atmospheric phenomena on ToF imaging is critical to identify effective correction s…
Investigating Intense Rainfall Influence on Distance Measurement with a Time-of-Flight Camera Sensor Using Optical Ray-Tracing Simulation Technique Open
Robust, fast and reliable examination of the surroundings is essential for further advancements in autonomous driving and robotics. Time-of-Flight (ToF) camera sensors are a key technology to measure surrounding objects and their distances…
Sintering strategies for inkjet printed metallic traces in 3D printed electronics Open
Emerging from 2D printed electronics, 3D printed electronics promise a break-through in additive manufacturing and prototyping of electronics. However, transferring the know-how from 2D flexible electronics to 3D parts with complex structu…
Simulating Rain Droplets Influence on Distance Measurement with a Time-of-Flight Camera Sensor Open
Time-of-Flight (ToF) camera sensors measure simultaneously the light intensity and the scene distance on a pixel basis. Environmental effects, like rain droplets between the scene and the ToF camera, have an impact on the distance accuracy…
