The Future in Sightby Brian Wowk Oct. The year is 2. 02. You are standing on a platform at the edge of a thousand foot cliff overlooking the Tharsis volcano range on Mars. Your body casts a long shadow in the light of the setting sun as you scan the horizon for interesting features with your binoculars. Walking toward the edge of the precipice, you survey the texture of the rusty red boulders around you. Butterflies rise in your stomach as you peer over the cliff edge. In the fall of 1964, on a visit to the Worlds Fair, in Queens, Lewis Altfest, a twentyfiveyearold accountant, came upon an openair display called the Parker.

Crystalis Institute is an educational and spiritual institution dedicated to serving the Light. The Institute was founded by Naisha Ahsian for the purpose of. Sixteen hundred miles overhead, Phobos, one of the Martian moons shines conspicuously. There is a new transport base under construction there. You move toward your telescope to get a better view, when suddenly a doorway materializes out of empty space A leg steps through it. Its your wife with dinner. Of course, you were never really on Mars. The platform you were standing on was merely the floor of a small, comfortably furnished room called a teleporter. The walls and ceiling of this room are covered with one of the technological wonders of the 2. Theory. Phased array optics is a technology that will produce three dimensional views of objects and scenery using only two dimensional displays. After decades learning about the laws of abundance and using this information to help countless clients, students, even family and friends Its my belief that. Contact Valley Voices.

Display systems based on this technology optical phased arrays will behave quite literally as windows onto whatever scenery we can imagine. Phased arrays are based on the theory of diffraction from physical optics. This theory says that patterns of light waves travelling beyond an aperture such as a window are entirely determined by the amplitude and phase distribution of light at the surface of the aperture. This means that if we produce light with the right phase and brightness distribution across a two dimensional surface, we can reproduce the same light waves that would emanate from a three dimensional scene behind the surface. In other words, we can make that surface appear as a window onto the scene. Diffraction theory is mathematically continuous it is assumed that surfaces can be reduced to an infinite number of small elements radiating with different amplitude and phase. This introduces complications from the standpoint of developing a practical technology. Within this complex, convoluted, infinite vastness of quantum space and time are there fixed points that we will travel to no matter what path we take The steps to manifestation can be a simple yet complex undertaking. There are numerous variations to the process of manifesting and manifestation, but 6 principles.

Whatever youre going through, whatever problems you feel are impossible to overcome, however much youve tried and failed in the past, however little experience. Infinite Abundance Program' title='Infinite Abundance Program' />Fortunately we can achieve the same results with a discrete array of sources, provided they are coherent and less than 12 wavelength apart. The wavelength of visible light ranges from 0. A two dimensional array of programmable sources 0. Figure 1 illustrates the reconstruction principle in two dimensions for a few simple cases. In Fig. 1a all the sources radiate with the same amplitude and phase. Their waves interfere to create a plane wave propagating normal to the surface. This is the type of wave that would be produced by a distant point source. In Fig. 1b there is a linear variation of phase among the sources down the line. The result is a plane wave propagating at an angle to the surface. By adjusting the amount of phase variation, we can steer this beam in any direction we please. In Fig. 1c a more complicated phase relationship is used to produce a spherical wave, creating the image of a point source near the surface. By choosing the correct phase and amplitude distribution across the array we can, in fact, create images of any number of points at any number of locations behind the array. Since any three dimensional scene can be represented as a collection of discrete points in space, it follows that our array can reproduce any three dimensional scene. Hp Designjet 500 Belt Installation. The procedure for calculating the phase and amplitude distribution required to produce a scene is straightforward. All visible objects in the scene are represented in a computer in terms of discrete surface points. The spacing of the points is determined by the resolution of the array. Each point is assumed to produce a spherical wave. The complex amplitudes of these waves are summed at each source position on the array. The resultant complex amplitude at each source point determines the phase and intensity that source must radiate to reproduce the scene. Design. The sources in a phased array must radiate coherently. That is, they must be able to interfere with each other. The easiest way to achieve this is to illuminate the back of the array with light from a single laser. A diverging laser beam could be aimed at the array from behind, or the beam could be transported through a thin planar waveguide on the rear surface of the array. Since lasers can be made with coherence lengths of kilometers, it doesnt really matter how the laser light gets to the sources. It will always be coherent across the array, and each source can have its own phase and amplitude calibration factors. In this scheme, each source in the array is a passive transmission element with adjustable optical path length phase and transmission amplitude. Fig. 2 shows a cross section through a few elements. The elements are 0. A bacterium could cover five of them. Each element consists of a phase shifter and an amplitude modulator. The amplitude modulator is simple. A cross polarizer like those in LCD displays should suffice. The phase shifter is made of an electrooptic birefringent material. This means that the shifter changes its refractive index along one polarization direction in response to an electric field. A polarizing filter down the back of the array ensures light of the proper linear polarization enters the shifter. A quarter wave plate on the front of the array to restore elliptical polarization is optional. A large variety of crystals are known to exhibit the required electrooptic effect Kaminow 1. Some of these are semiconductors that are the stock in trade of existing microfabrication technology. Unfortunately the electrooptic effect in solid crystals is rather weak. Even very large electric fields produce very small changes in refractive index. If I Ever Fall In Love Again Shai there. Since each phase shifter must be able to retard light passing through it by one full wavelength, a small change in refractive index means a long phase shifter. For solid crystals this length will be on the order of a millimeter, which is probably too long to be practical. Nematic liquid crystals exhibit an electrooptic effect thousands of times stronger than that found in solids Kahn 1. If these crystals can be made with a high refractive index and fast response, then phase shifters one micron long like those in Fig. An interesting alternative has been suggested by Jeffrey Soreff of IBM Soreff 1. Rather than relying on electrooptic effects, a crystal with a large fixed birefringence, such as calcite, could be used. The crystal is sandwiched between parallel linear polarizers, and rotated relative to the direction of polarization. The phase shifting rotation could be accomplished by mechanical rotation of the crystal, or by rotating the polarizer directions. This scheme would also permit micron length phase shifters. In all these designs each phase shifter is behaving as a waveguide near cutoff. Red light, with a wavelength in free space of 0. To get through a waveguide less than 0. This will require a refractive index of at least 1. Data Management. While the synthesis of array images may be mathematically simple, it will be computationally severe by 1. A source separation of 0. Each one of these sources will have to radiate with its own calculated phase and amplitude. This is a staggering amount of information. Fat Burning Workout Program.
