Encoding amplitude information onto phase-only filters

JA Davis, DM Cottrell, J Campos, MJ Yzuel… - Applied optics, 1999 - opg.optica.org
We report a new, to our knowledge, technique for encoding amplitude information onto a
phase-only filter with a single liquid-crystal spatial light modulator. In our approach we …

Encoding amplitude and phase information onto a binary phase-only spatial light modulator

JA Davis, KO Valadéz, DM Cottrell - Applied optics, 2003 - opg.optica.org
We report what to our knowledge is a new technique for encoding both amplitude and phase
information onto a single binary-valued spatial light modulator. In our approach, we spatially …

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

A Bergeron, J Gauvin, F Gagnon, D Gingras… - Applied …, 1995 - opg.optica.org
A simple phase-characterization method for spatial light modulators is proposed. The low-
cost method permits high-precision measurement and provides data for the setting of the …

Pattern recognition with binary phase-only filters

JL Horner, JR Leger - Applied Optics, 1985 - opg.optica.org
It has been noted previously that the diffraction efficiency of a spatial filter can be an
important system constraint. Limited filter illumination or a highly multiplexed impulse …

Image processing with the radial Hilbert transform: theory and experiments

JA Davis, DE McNamara, DM Cottrell, J Campos - Optics letters, 2000 - opg.optica.org
The Hilbert transform is useful for image processing because it can select which edges of an
input image are enhanced and to what degree the edge enhancement occurs. However, the …

Complex amplitude modulation by use of liquid-crystal spatial light modulators

JLDB De La Tocnaye, L Dupont - Applied Optics, 1997 - opg.optica.org
We propose to study the conditions for implementation of complex amplitude modulation on
standard liquid-crystal spatial light modulators when illuminated by polarized light. The …

Analysis of programmable ultrashort waveform generation using liquid-crystal spatial light modulators

MM Wefers, KA Nelson - JOSA B, 1995 - opg.optica.org
A rigorous analysis of ultrashort pulse shaping by the spectral filtering of dispersed
frequency components is presented. Particular attention is directed toward the case of two …

Two-dimensional polarization encoding with a phase-only liquid-crystal spatial light modulator

JA Davis, DE McNamara, DM Cottrell, T Sonehara - Applied Optics, 2000 - opg.optica.org
We show how to two dimensionally encode the polarization state of an incident light beam
using a parallel-aligned liquid-crystal spatial light modulator (LCSLM). Each pixel of the …

Reducing the effect of pixel crosstalk in phase only spatial light modulators

M Persson, D Engström, M Goksör - Optics express, 2012 - opg.optica.org
A method for compensating for pixel crosstalk in liquid crystal based spatial light modulators
is presented. By modifying a commonly used hologram generating algorithm to account for …
