Item Stokes polarimeter using vector diffractive optical elements(2023) Soria García, Ángela; Del Hoyo Muñoz, Jesús; Sánchez Brea, Luis Miguel; Pastor Villarrubia, Verónica; González Fernández, Verónica; Elshorbagy, Mahmoud H.; Alda Serrano, JavierWe designed, fabricated and tested a Vector Diffractive Optical Element (VDOE) to simultaneously determine the Stokes vector of light. It comprises several sectors. Each one is a vector Fresnel zone plate which focuses the light on separate foci and has different polarization properties. The polarization state is calculated from their intensities. From simulations, we could identify the error sources that were analytically removed. The residual uncertainty after applying our corrections was as low as 6x10^(-5). The uncertainty obtained for our fabricated VDOE, 3.33 %, is competitive with the results from state-of-the-art techniques.Item Calibration of the complete Jones matrix of SLMs(Proceedings of SPIE, 2021) Hoyo Muñoz, Jesús del; Sánchez Brea, Luis Miguel; Soria García, ÁngelaSpatial light modulators are very common in many applications. They are used to implement amplitude, phase and polarization masks. In order to optimize its performance, it is important to characterize it, which means determining its Jones matrix. Here we present a method which consists on performing several intensity measurements for each gray level. It is simple enough that can be quickly performed, but offers much better results than previous methods.Item Calibration method to determine the complete Jones matrix of SLMs, Corrigendum (vol 151, 106914, 2022)(Optics and lassers in engineering, 2023) Hoyo Muñoz, Jesús del; Sánchez Brea, Luis Miguel; Soria García, Ángela
