A Tutorial on Structured Light's Generation and Characterization

Structured light has gained popularity over the past two decades across various research fields. The potential of its fascinating properties has provided new perspectives for both previously unforeseen and well-established applications. Crucial to this are the several proposed techniques for their generation and characterization, for which the invention of computer-controlled devices has been pivotal.

In this tutorial-like webinar hosted by the Holography and Diffractive Optics Technical Group, Carmelo Rosales-Guzmán will provide a technical how-to on scalar and vectorial light fields generation and characterization. The webinar is intended for both those using spatial light modulators for the first time and those interested in learning more advanced techniques. Toward the end of the webinar, Dr. Rosales-Guzmán will provide specific examples of key applications where structured light is particularly promising, such as optical metrology. Finally. Dr. Rosales-Guzmán will share his perspective on possible directions structured light’s applications might take.
