Beam steering is the process of controlling the direction of a laser or light beam by manipulating its properties to achieve desired results.
Breaking the barriers of conventional optical components, a team of researchers has developed an ultrathin metasurface beam splitter that can split light into two predesigned directions with variable power distribution.
Dynamic optical beam-steering of a band-edge chiral nematic liquid crystal (LC) laser has been demonstrated, achieved through the use of tuneable nematic LC phase shifters and fixed polarisation gratings.
In this article, we will explore the different types of laser beam steering techniques and their applications.
