An autostereoscopic head-tracked back projection display that uses an RGB laser illumination source and a fast light engine is described. Images are horizontally scanned columns controlled by a spatial light modulator that directs two or more images in the directions of the apposite viewers’ eyes.

We manipulate a Bose-Einstein condensate using the optical trap created by the diffraction of a laser beam on a fast ferro-electric liquid crystal spatial light modulator. The modulator acts as a phase grating which can generate arbitrary diffraction patterns and be rapidly reconfigured at rates up to 1 kHz to create smooth, time-varying optical potentials. The flexibility of the device is demo...

In today’s information technology infrastructures Service Level Management (SLM) is considered a vital discipline of IT Service Management. Only by having a framework for establishing a common understanding of services and the manner in which they are used and provided, can next generation IT infrastructures (e-Infrastuctures) maintain a sufficient “customer satisfaction” on a sustainable level...

Data files: Open the data file, most of the time in CZI format or ome.tiff and translate into TIF. The TIF file contains 32 channels of Uint16 in a sequence. They must be converted to a single file in the format “.B64”. Routines for the conversions are available in SimFCS. If the data from the SLM 880 were stored as ome.tiff, you can use these files but first they need to be converted into B64....

Reliable application of spatial light modulators (SLMs) as programmable diffractive optical elements requires a thorough calibration. In this paper, we propose a method for calibrating SLMs based on the evaluation of Fresnel images. Fresnel images generated by a binary phase diffraction grating consist of binary irradiance distributions whose visibility depends on the phase modulation. By displ...

Arbitrary complex-valued functions can be implemented as arrays of individually specified diffusers. For any diffuser, only average step height and vertical roughness are needed to control phase and amplitude. This modulation concept suggests potentially low-cost fabrication methods in which desired topographies are patterned by exposing photoresist with partially developed speckle patterns. An...

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 liquid-crystal spatial light modulators used to provide programmable manipulation of both the phase and the amplitude profiles of the shaped waveform in the time domain. Different optical configurations are evaluated an...

Random lasers are exotic light sources that emit coherent light without any of the confining mirrors that are part of a conventional laser.1, 2 Instead, the light inside a random laser is trapped by multiple scattering in a disordered medium and can thus be efficiently amplified. The downside is that random lasers emit their light at many different frequencies and in many different directions (...

This article presents the strategic learning meta-model (SLM). We describe the architecture of the SLM, which consists of three layers: reactive layer, intelligent layer and infrastructure layer. The purpose of this paper is to present the reactive layer of the SLM and in particular the model that constitutes: the regulation model. This model was tested with a series of cases which indicate an ...

There are a number of manufacturing methods used for the manufacture of control valve trim components, some of which are expensive processes. Current market conditions and increased competition requires manufacturers to reduce costs of these components and they are investigating new technologies such as processes using Additive Layer Manufacturing (ALM) to produce these components. These proces...
