Optical design of static and dynamic laser beam shaping systems
SPIE Proceedings, 2015Many commercial, medical and scientific applications of the laser have been developed since its invention. Materials processing applications, like cutting or welding; and medical applications, like corneal surgery are just a few examples that may require a specific beam irradiance distribution to ensure optimal performance.

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.

Dynamic shape control of sub-sections of moderately thick beams
Computers & Structures, 2005The present paper is concerned with dynamic shape control of Timoshenko beams by self-stress actuation. In many practical applications, it is sufficient to control a sub-section of the beam by self-stress actuation applied only within the sub-section.

Minimum dynamic response for a class of simply supported beam shapes
International Journal of Mechanical Sciences, 1968Abstract The problem involves a simply supported beam of constant total mass with a cross-section varying along the length and loaded four different ways (point impulse at the centre, uniformly distributed impulse along the length and again these two loads applied at t = 0 but persisting). It is desired to find the minimum-maximum dynamic deflection
