Beam Steering Using Active Artificial Magnetic Conductors: A 10-Degree Step Controlled Steering

Fast - steering mirrors improve active beam stabilization

nce solely a research tool, the laser is now an enabling technology for a wide range of applications in semiconductor manufacturing and inspection, industrial marking, materials processing, biomedical systems, reprographics, information display, and telecommunications. Given today’s accelerated product-development schedules, laser-based optical systems are being pushed to produce finer resoluti...

Broadband Beam Steering

A solid-state broadband beam deflector is described. This non-mechanical system steers spatially coherent broad band light to a common location in the far field. The components include a liquid crystal grating and achromatic Fourier transformer. The liquid crystal grating employs a polarization modulation scheme which produces a wavelength independent phase shift. The achromatic Fourier transfo...

High-resolution beam steering using microlens arrays.

Imaging or beam-steering systems employing a periodic array of microlenses or micromirrors suffer from diffraction problems resulting from the destructive interference of the beam segments produced by the array. Simple formulas are derived for beam steering with segmented apertures that do not suffer from diffraction problems because of the introduction of a moving linear phase shifter such as ...

Systemsicherheit des Active Front Steering (Active Front Steering - System Safety)

Active Front Steering ist ein elektronisch geregeltes Lenksystem für Kraftfahrzeuge, das situationsabhängig eine Überlagerung eines Winkels zum Lenkradwinkel erlaubt und somit eine Variation der Lenkübersetzung ermöglicht. Für ein solches System muss die funktionale Sicherheit gewährleistet sein. Ziele der funktionalen Sicherheit werden erläutert und messbare Kriterien und deren Nachweisbarkeit...
