Item Fabrication effects in the optical performance of DOEs engraved with femtosecond lasers(Proceedings of SPIE, 2021) Soria García, Ángela; Fantova, Jorge; San Blas, Alejandro; Hoyo Muñoz, Jesús del; Sánchez Brea, Luis Miguel; Alda Serrano, Javier; Rodríguez González, Ainara; Olaizola Izquierdo, Santiago M.The development of DOEs fabrication techniques is continuously growing due to the wide range of industrial applications, such as beam manipulation or optical position encoders. In this work, we use Femtosecond laser direct writing to manufacture DOEs, which uses a simpler and more efficient way to fabricate amplitude binary masks. Also, we have analyzed the performance of the DOEs. The fabrication technique is validated since the experimental results are in accordance to numerical simulations.Item Calibration method to determine the complete Jones matrix of SLMs(Optics and Lassers in Engineering, 2021) Hoyo Muñoz, Jesús del; Sánchez Brea, Luis Miguel; Soria García, ÁngelaWe present a simple method to determine the polarimetric properties of spatial light modulators (SLMs) for each grey level by means of irradiance measurements. The Jones matrix of the SLM is obtained without any assumption about its properties, so it can be applied for more devices than previous works. This method is simple enough to be quickly performed, while offers better results than previous works, as it reduces the error in the prediction of transmission intensities in a factor between 5 and 380.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
