Closed-loop dynamic shape control of a flexible beam
SPIE Proceedings, 1990An experimental implementation of a new distributed parameter shape control design methodology is presented. The technique is based upon the input/output representation of distributed parameter systems in a spatially- and temporallytransformed frequency space.

Dynamic control of laser beam shape for heat treatment
Journal of Laser Applications, 2018One of the major challenges for laser hardening is dealing with the geometrical singularities of the treated components. The problem arises from the laser hardening of uneven surfaces such as those with sharp edges or holes. In these cases, due to the differences in the surrounding volume of the material, overheating problems often appear leading to ...

Dynamic beam shaping with coherent beam combining
PhotonicsViewsAbstractCoherent beam combining (CBC) is a method of enhancing laser power. It has recently transitioned to industrial applications, unveiling new possibilities in laser technology. CBC merges multiple laser channels from a single source, controlling their phase to create constructive or destructive interference.

The authors demonstrate a technique to optically imprint through linear beam propagation an index pattern in the bulk of a photorefractive crystal capable of beam reshaping and waveguiding. The procedure is based on the separation into two distinct phases of the photosensitive and refractive response, so that light is in all cases undergoing only ...

Dynamic MEMS-based linear (1D) diffusers for laser beam homogenizing and beam shaping
SPIE Proceedings, 2009We present a dynamic laser beam shaper based on MEMS technology. We show a prototype of a dynamic diffuser made of single crystal silicon. A linearly deformable silicon micromembrane is used to diffuse a laser beam in one dimension. Resonance frequencies of the membrane can range from 1 kHz to 100 kHz.

Compact dynamic phase-modulation system for laser beam splitting and beam shaping
2002A two-dimensional dynamic phase-modulating system (DPS) addressed by a digital signal at video frame rate can realize several optical transmission functions in the field of refractive as well as diffractive optics. Critical parameters are the space-bandwidth product, the phase shift and the light efficiency of the system.
