Headlamp innovations: Optical concepts for fully adaptive light distributions

Knöchelmann, Marvin; Kloppenburg, Gerolf; Lachmayer, Roland (Bellingham, Wash. : SPIE, 2018)

Glare avoidance and marking lights are two of the many functionalities offered by advanced automotive headlamps such as Matrix-LED systems. DMD-based headlamps offer resolution enhancements to these two adaptive lighting ...
Investigation and enhancement of the detectability of flaws with a coarse measuring grid and air coupled ultrasound for NDT of panel materials using the re-radiation method

Schmelt, Andreas Sebastian; Marhenke, Torben; Hasener, Jörg; Twiefel, Jens (Basel : MDPI AG, 2020)

Non-destructive ultrasonic testing is utilized widely by industries for quality assurance. For sensitive materials or surfaces, non-contact, non-destructive testing methods are in demand. The air-coupled ultrasound (ACU) ...
Superresolved femtosecond laser nanosurgery of cells

Pospiech, Matthias; Emons, Moritz; Kuetemeyer, Kai; Heisterkamp, Alexander; Morgner, Uwe (Washington, DC : Optical Society of America, 2011)

We report on femtosecond nanosurgery of fluorescently labeled structures in cells with a spatially superresolved laser beam. The focal spot width is reduced using phase filtering applied with a programmable phase modulator. ...
