“…We implemented experimentally CGHs that encode Bessel and Laguerre-Gauss beams. In this task we employed a twisted nematic liquid crystal device as a phasemostly SLM employing a linear polarizer followed by a quarter wave plate at the input, and a second linear polarizer at the output [9]. The phase modulation depth obtained when a He-Ne laser {/i=633 nm) is employed as illuminating source was =1.2?!.…”

“…The twisted angle and the birefringence of a TNLC are two main parameters that control the modulation. There are several proposed methods and configurations to find these parameters to introduce the Jones matrix of TNLC [22][23][24][25][26]. On the contrary, Martín-Badosa et al proposed a method to characterize liquid crystal displays (LCDs) based on the fringe analysis obtained by a Mach-Zehnder interferometer configuration, without the necessity of finding the physical properties of LCD [27].…”

This chapter describes an efficient approach to generating light beams with arbitrary intensity profile and phase distribution. Accordingly, a fast method is described to characterize liquid crystal displays based on the Mach-Zehnder interferometer and fringe analysis in the Fourier domain. Then, the double-pixel hologram Arrizón’s approach is reviewed. This approach is able to generate an on-axis computer-generated hologram into a low-resolution twisted-nematic liquid crystal for encoding arbitrary complex modulations. Furthermore, a fast algorithm to map holographic cells based on the k-nearest neighbor (k-NN) classifier is introduced in order to generate computer-generated holograms faster than the conventional calculation. Finally, two beam profiles are produced with the described approach and assessed at the entrance pupil and the depth of focus of a high-NA microscope objective.
