31light — light1 lightful, adj. lightfully, adv. /luyt/, n., adj., lighter, lightest, v., lighted or lit, lighting. n. 1. something that makes things visible or affords illumination: All colors depend on light. 2. Physics …
32Fourier optics — is the study of classical optics using techniques involving Fourier transforms and can be seen as an extension of the Huygens Fresnel principle. The underlying theorem that light waves can be described as made up of sinusoidal waves, in a manner… …
33laser — /lay zeuhr/, n. Physics. a device that produces a nearly parallel, nearly monochromatic, and coherent beam of light by exciting atoms to a higher energy level and causing them to radiate their energy in phase. Also called optical maser. [1955 60; …
34History of optics — Optics began with the development of lenses by the ancient Egyptians and Mesopotamians, followed by theories on light and vision developed by ancient Greek and Indian philosophers, and the development of geometrical optics in the Greco Roman… …
35Laser applications — There are many scientific, military, medical and commercial laser applications which have been developed since the invention of the laser in the 1958. The coherency, high monochromaticity, and ability to reach extremely high powers are all… …
36Worm-like chain — The worm like chain (WLC) model in polymer physics is used to describe the behavior of semi flexible polymers; it is sometimes referred to as the Kratky Porod worm like chain model. Theoretical Considerations The WLC model envisions an isotropic… …
37Mark G. Raizen — Mark George Raizen is a physicist who conducts experiments on quantum optics and atom optics. Contents 1 Birth and Education …
38Solar sail — Solar sails (also called light sails or photon sails, especially when they use light sources other than the Sun) are a proposed form of spacecraft propulsion using large membrane mirrors. Radiation pressure is about 10 5 Pa at Earth s distance… …
39Laser cooling — refers to the number of techniques in which atomic and molecular samples are cooled through the interaction with one or more laser light fields. The first example of laser cooling, and also still the most common method of laser cooling (so much… …
40Dielectrophoresis — (or DEP) is a phenomenon in which a force is exerted on a dielectric particle when it is subjected to a non uniform electric field.[1][2][3][4][5] This force does not require the particle to be …
