Vectorial holography for independent intensity and polarization control

Optics Letters, 2023
Metasurface-based vectorial holography can reconstruct images with different polarization states. However, the number of polarization channels in the holographic image is relatively small in traditional methods. Here, we propose and demonstrate a metasurface vectorial hologram which carries infinite polarization channels.

Spatio-temporal structuring control of a vectorial focal field

Applied Optics, 2023
Focal field modulation has attracted a lot of interest due to its potential in many applications such as optical tweezers or laser processing, and it has recently been facilitated by spatial light modulators (SLMs) owing to their dynamic modulation abilities. However, capabilities for manipulating focal fields are limited by the

Voltage vectorial control of an induction motor drive

IEEE International Symposium on Industrial Electronics. Proceedings. ISIE'98 (Cat. No.98TH8357), 2002
The paper describes a vectorial control strategy for induction motor fed by VSI which allows to exploit the dynamic performances by taking into account both the rotor and stator time constant, and avoiding at the same time the use of current control loop.

Vectorial control of a Voltage Source Converter

2010 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America (T&D-LA), 2010
The Voltage Source Converter (VSC) offers the possibility of full four quadrant operation and the total control active and reactive power with the minimal generation of harmonics with the SPWM technique. This paper presents the dq transformation of a VSC and its design of a vectorial control to regulate the DC voltage and reactive power in a rectifier ...
