Three-dimensional parallel holographic micropatterning using a spatial light modulator.
We present a micropatterning method for the automatic transfer and arbitrary positioning of computer-generated three-dimensional structures within a substrate. The Gerchberg-Saxton algorithm and an electrically addressed spatial light modulator (SLM) are used to create and display phase holograms, respectively. A holographic approach to light manipulation enables arbitrary and efficient paralle...
متن کاملDesign of Periodic Structures in a Multiple Beam Interference Scheme
Based on holographic interferometry technique, we develop an alternative method for micrometer-sized periodic structures design. The optical setup with 2D spatial light modulator for periodic structures generation is presented. It is shown that this innovative method made possible the rapid generation of periodic structures employing diffractive masks and phase modulation based on multiple beam...
متن کاملSpatial light modulator considerations for beam control in optical manipulation applications
Holographic beam forming to generate and control multiple optical traps has proved successful using high-resolution spatial light modulators (SLMs). This type of beam control allows a multitude of traps to be independently controlled in three dimensions. Also, exotic beam shapes and profiles can be generated, which gives the optical trapping system even greater flexibility. Until recently, the ...
متن کاملMaskless photolithography via holographic optical projection.
We propose an inexpensive novel rapid prototyping approach to a maskless and fully adaptive photolithographic process. Phase-only computer-generated holograms of lithographic masks displayed on a liquid-crystal-on-silicon spatial light modulator were used in a holographic optical lithography system. Using holographic projection allows diffraction-limited performance within the given parameters ...
متن کاملPosition and Intensity Modulations in Holographic Optical Traps Created by a Liquid Crystal Spatial Light Modulator
The addressing of the liquid crystals in spatial light modulators gives rise to temporal modulation of the phase pattern. Here we investigate the effect of this on the intensity and position of holographic optical traps. We use high-speed camera imaging of the laser spots back-reflected off the sample cover slip to determine the integrated pixel intensity and track the position of a laser spot....
