Abruptly autofocusing vortex beamsJeffrey A Davis
Department of Physics, San Diego State University, San Diego, California 92182 1233, USA
Opt Express 20:13302-10. 2012..Finally we show how to move the focus spot in three dimensions by encoding additional optical elements onto the phase pattern...
Ray matrix analysis of the fast Fresnel transform with applications towards liquid crystal displaysJeffrey A Davis
Department of Physics, San Diego State University, San Diego, California 92182 1233, USA
Appl Opt 51:644-50. 2012..We show two examples that confirm our ideas. We expect that these results will be very useful for computational comparison with experimental studies of a variety of diffraction phenomena...
Observation of accelerating parabolic beamsJeffrey A Davis
San Diego State University, Department of Physics, San Diego, CA 92182 1233, USA
Opt Express 16:12866-71. 2008..The amplitude and phase masks required to generate these beams are encoded onto a single liquid crystal display. Experimental results agree well with theory...
Circular-polarization-splitting common-path interferometer based on a zero-twist liquid-crystal displayJeffrey A Davis
Department of Physics, San Diego State University, San Diego, California 92182 1233, USA
Opt Lett 34:1486-8. 2009..Using a linear polarizer, these two beams form an interferogram that can be used to analyze optically active media. Experimental results are provided showing the detection of left-handed-rotary and right-handed-rotary media...
Generation of accelerating Airy and accelerating parabolic beams using phase-only patternsJeffrey A Davis
Department of Physics, San Diego State University, San Diego, California 92182 1233, USA
Appl Opt 48:3170-6. 2009..Finally we incorporate the Fourier transform lens onto the mask. We obtain excellent experimental results with a phase-only pattern and a shorter optical system. This approach makes these beams much easier to implement...
Fourier transform pupil functions for modifying the depth of focus of optical imaging systemsJeffrey A Davis
Department of Physics, San Diego State University, San Diego, California 92182, USA
Appl Opt 48:4893-8. 2009..Finally we multiply our original pupil function by an edge-enhancing window function. Now the pupil function produces two sharp focus spots at the locations corresponding to the edges of the rectangle function...
Effects of the optical system on the output from wavefront coding masksJeffrey A Davis
Department of Physics, San Diego State University, San Diego, California 92182 1233, USA
Opt Express 19:17677-82. 2011..We review the similarities and critical differences between various optical systems and show computational results. We suggest new directions for improving the performance of these wavefront coding masks...
Fraunhofer diffraction of a partially blocked spiral phase plateDon M Cottrell
Department of Physics, San Diego State University, San Diego, California 92182 1233, USA
Opt Express 19:12873-8. 2011..In this work, we present an explanation of this effect based on careful examination of classical diffraction theory and show new experimental results. This approach is very convenient for easily determining the sign of the vortex charge...
Direct generation of abruptly focusing vortex beams using a 3/2 radial phase-only patternJeffrey A Davis
San Diego State University, Department of Physics, San Diego, California 92182 1233, USA
Appl Opt 52:1888-91. 2013..The resulting optical system is much shorter. In addition, we can easily produce vortex patterns at the focal point of these beams. Experimental results match theoretical predictions...
Creating three-dimensional lattice patterns using programmable Dammann gratingsJeffrey A Davis
Department of Physics, San Diego State University, San Diego, California 92182 1233, USA
Appl Opt 50:3653-7. 2011..We demonstrate the generation of five planar arrays each having 6×6 points surrounding another set of four planar arrays each having 5×5 points with a single pattern...
