Extractions: Excerpt: 5 Modern medicine treats the human body like a car not knowing who the driver is. A driver can get out of the car and leave it running, something similar happens when we sleep. The car must have a driver to move in a purposeful manner. As this driver, or the mind, exists independent of the physical body, it may be said to correlate to ideas of a soul or spirit Modern medicine is missing the most important parameter in the definition of lifethe existence of a soul. A mystical experience is an experience of merging with God or the cosmic spirit. Many religions emphasize the gulf between God and Creation; however, the mystic experiences no such gulf. He or she has experienced being one with God or merging with the cosmic spirit. From a philosophers perspective the idea is that what we usually call I is not the true I. In short glimpses, we can experience an identification with a greater I. Some mystics call it God; others call it the cosmic spirit, nature or the universe. However, having a mystical experience with the One in a house of worship

A new date will be announced on this webpage shortly Introduction Programme To Register Supra molecular materials in the form of electro-active polymers and liquid crystals are starting to make inroads into photonic and electronic devices. The first liquid crystal components have been installed in the optical transmission network. New polymers are the basis of very high-speed electro-optic modulators, new emissive sources and guided wave devices. New applications of liquid crystals in microwave devices are being investigated. Techniques of real-time holography and adaptive optics are being opened up using spatial light modulators and investigated for applications in telecom and datacom systems. With the displays industry and microelectronics, as well as Photonics, industries (and strategic planning) all set to adopt molecular materials into functional applications there has never been a greater need to coordinate activities in this field. Optical interconnect at the back-plane, board and, even, chip-level seem certain to precede active optical technology in these applications. The displays industry is targeting flexible electronics inclusive of "organic TFT" as a strategic necessity driven by manufacturing cost and applications requirements. Optical processing engines enabled by LCOS technology, optical storage based on photo-refractivity in polymers and liquid crystals all seem set to drive revolutions in the usage and market penetration of molecular materials.

(includes guestbook) Introduction Manipulation of cold atoms is carried out with either magnetic fields or with optical fields. Both play a part in the creation of cold atoms, but both are also very useful in the guiding, transport, focussing and deflection of the atoms. This is a topic known as atom optics. Magnetic manipulation of atoms has some advanatges over that of optical manipulation, namely that magnetic fields are easier to shape and dynamically control than optical fields. It's difficult to make a curved light beam for instance. Here we a discuss a method to create more versatile and dynamically controlable light fields using spatial light modulators (SLMs). Spatial Light Modulators A SLM can be thought of as a pixellated variable waveplate, with each pixel acting as an indivdual waveplate. As such the SLM can act in two different modes, in an amplitude modualtion mode and a phase modualtion mode. The modualtion is achieved by 'writing' the desired pattern to the SLM either optically (pattern is imaged through an LCD onto the SLM) or electrically (pixels are addressed indivdually) and the light intensity/applied voltage present at the SLM deticates the amount of modulation at that particular point.

Holography With Photorefractive Polymers The figure below shows schematically how to make a hologram a speed roughly proportional to the average light energy. Return to photonics Laboratory homepage. http://www.users.drew.edu/~dmcgee/holography_with_polymers.html
Extractions: chemical change in a light-sensitive film. After processing, the film (now a print) is a reasonably good record of the intensity of light emitted or reflected from all points of the object. A photograph lacks depth perception, however, because the chemical film can only respond to the time-averaged light energy leaving the object. If however, the light leaving the object is mixed with a known reference light, then the time-averaged light energy in the film will contain a code that when replayed will duplicate the 3-dimensional depth of the original object. In the language of physical optics, this code is the interference pattern (also called a hologram) that results when the object light and reference light mix in the photographic film. The figure below shows schematically how to make a hologram: The key to both photography and holography is the chemical film that responds to the time-average light energy. Photorefractive materials are analogous in many respects to photographic film. After processing, photographic film becomes dark in those regions exposed to relatively low light energy, and bright in regions exposed to higher light energy. Photorefractive materials exhibit a change in their index of refraction (i.e. a measure of the speed of light) proportional to the time-averaged light energy. There is one key difference between photographic film and photorefractive film: photorefractive film requires no processing- the response occurs in real-time, with a speed roughly proportional to the average light energy.

Extractions: Frequently Asked Questions (FAQs) Holography and Diffractive Optics FAQs What is holography? Holography is a method for recording the optical field distribution that results from the light scattered by an object. The recording medium that contains the field information is called a hologram. Since there is a one-to-one correspondence between the object and its scattered field, a hologram can be used to reconstruct the optical field distribution of the object. As the field information contains spatial information about the object the hologram can give a 3D spatial image of the recorded object if it is illuminated with coherent light. What is a computer-generated hologram (CGH)? The physics of holography can be efficiently simulated on modern computer systems. This can be used to compute the field distributions of virtual reality objects and the corresponding hologram distributions. These distributions are digital and can be recorded on a holographic medium. The result is a computer-generated hologram. If it is illuminated with coherent light, the virtual reality object can be made visible. Is "the Holodeck" possible?
