We develop an improved phase calibration method of a reflective spatial light modulator (SLM) using interferometry by employing novel phase masks. We generate the optimised phase masks by using Iterative Fourier Transform Algorithm (IFTA) and demonstrate that they perform with 18$\%$ better efficiency over global linear corrections in the look-up table (LUT). In addition, we also implement global linear corrections in the LUT and correspondingly modify the phase encoding of blazed gratings to…

Experimental realization of scalar and vector perfect Laguerre–Gaussian beams

The generation of a perfect optical vortex (POV) has been an important area of research since the concept was introduced by Ostrovsky et al. [Opt. Lett. 38, 534 (2013)]. In this Letter, we provide

Holographic Encryption Applications Using Composite Orbital Angular Momentum Beams

Optical orbital angular momentum (OAM) holography has been developed and implemented as a vital method for optical encryption. However, OAM holography can only be encoded and decoded with an OAM



Interferometric method for phase calibration in liquid crystal spatial light modulators using a self-generated diffraction-grating.

An auto-referenced interferometric method for calibrating phase modulation of parallel-aligned liquid crystal (PAL) spatial light modulators (SLM) is described, which uses the SLM itself to create a tilted plane wave and a reference wave which mutually interfere.

Calibration of spatial light modulators suffering from spatially varying phase response.

Compared to conventional phase conversion methods, the proposed method increases the control of the trap intensities in HOT, and efficiently prevents the appearance of strong unwanted 0th order diffraction that commonly occurs in SLM systems.

Optimisation of a low cost SLM for diffraction efficiency and ghost order suppression

Abstract Spatial Light Modulators (SLMs) are a powerful tool in many optics laboratories, but due to the technology required for their fabrication, they are usually very expensive. Recently some

Spatially resolved phase-response calibration of liquid-crystal-based spatial light modulators.

Methods for measuring and compensating the nonlinear electro-optical effect of transmissive, parallel-aligned liquid crystal (LC)-based spatial light modulators (SLMs) are presented and the LC-SLM's experimental demonstration finally verifies the resultant improvement in holographic imaging.

Phase calibration and applications of a liquid-crystal spatial light modulator.

The phase-phase correlator permits sharper correlation peaks, better energy transmission, and higher discrimination than an amplitude-phase correlation, and the dynamic phase response is used to perform efficient kinoform recording.

Characterization of the phase modulation property of a free-space electro-optic modulator by interframe intensity correlation matrix.

A simplified approach to characterize a phase modulator is proposed by investigating the performance of phase shifts from grabbed interferograms using the phase extraction method, and the interframe intensity correlation (IIC) matrix method is introduced.

Review of iterative Fourier-transform algorithms for beam shaping applications

A comparison of some of the most used iterative Fourier transform algorithms (IFTA) for the design of continuous and multilevel diffractive optical elements (DOE) is presented, and it is concluded that three of these algorithms are interesting for continuous-phase kinoforms.

Phase shifting interferometry using a spatial light modulator to measure optical thin films.

The experimental interferograms and the thicknesses of the thin film steps were successfully quantified, proving that this method can be used to measure thin films by applying the PSI method only on the region occupied by them.

Interframe intensity correlation matrix for self-calibration in phase-shifting interferometry.

The proposed method requires only four interferograms, unlike others, and can extract phase shifts reliably even from interferogram without well-defined fringes, such as speckle patterns.

Modulation light efficiency of diffractive lenses displayed in a restricted phase-mostly modulation display.

An analysis of the diffraction efficiency of diffractive lenses displayed on spatial light modulators that depends on the modulation response of the display is presented and it is demonstrated that the application of a minimum Euclidean projection principle leads to high modulation Diffraction efficiency even if the phase-modulation depth is much less than 2pi.
