Ballistic photons are the light photon s that travel through a scattering turbidity turbid optical medium medium in a straight line. Also known as ballistic light . If laser pulses are sent through a turbid medium such as fog or tissue biology body tissue , most of the photons are either randomly scattered or absorbed. However, across short distances, a few photons pass through the scattering medium in straight lines. These coherent photons are referred to as ballistic photons. Photons that are slightly scattered, retaining some degree of coherence physics coherence , are referred to as snake photons. If efficiently detected, there are many applications for ballistic photons especially in coherent high resolution medical imaging systems. Ballistic scanners using ultrafast time gates and optical coherence tomography OCT using the interferometry principle are just two of the popular imaging systems that rely on ballistic photon detection to create diffraction limited system diffraction limited images. Due to the exponential reduction with respect to distance of ballistic photons in a scattering medium, often image processing techniques are applied to the raw captured ballistic images, to reconstruct high quality ones.

Measuring setup is similar. A ballistic galvanometer is a type of mirror galvanometer . Unlike a current measuring galvanometer, the moving part has a large moment of inertia , thus giving it a low oscillation period. It is really an integrator measuring the quantity of charge discharged through it. It can be either of the moving coil or moving magnet type. Before first use the ballistic constant of the galvanometer must be determined. This is usually done by connecting to the galvanometer a known capacitor , charged to a known voltage and recording the deflection. The constant K is calculated from the capacitance C, the voltage V and the deflection d math K CV d math where K is expressed in coulombs per centimeter . In operation the unknown quantity of charge Q in coulombs is simply math Q kd math . Grassot Fluxmeter An interesting form of ballistic galvanometer is the Grassot fluxmeter. In order to operate correctly, the discharge time through the regular ballistic galvanometer must be shorter than the period of oscillation. For some applications, especially those involving inductors, this condition cannot be met. The Grassot fluxmeter solves this. Its construction is similar to that of a ballistic galvanometer, but its coil is suspended without any restoring forces in the suspension thread or in the current leads. The core bobbin of the coil is of a non conductive material. When an electric charge is connected to the instrument, the coil starts moving in the magnetic field of the galvanometer s magnet, generating an opposing e.m.f. and coming to a stop ... more details

Merge Ballistic conduction discuss Talk Ballistic transport Merger proposal date February 2009 Cleanup article date March 2008 Ballistic transport is the transport phenomena transport of electrons in a medium with negligible electrical resistivity due to scattering . Without scattering, electrons simply obey Newton s second law of motion at relativistic particle non relativistic speeds . In general, the resistivity exists because an electron, while moving inside a medium, is scattered by impurities, defects, or by the atoms molecules composing the medium that simply oscillate around their equilibrium position in a solid , or generically by any freely moving atom molecule composing the medium, in a gas or liquid. For a given medium one can associate to a moving electron a mean free path as the average length that the electron can travel freely, i.e. before hitting against something and deviating from its original path, possibly losing some kinetic energy . The mean free path can be increased by reducing the number of impurities in a crystal or by lowering its temperature except for some material like semi conductors . Ballistic transport is observed when the mean free path of the electron is much bigger than the size of the box that contains delimits the medium through which the electron travels, such that the electron alters its motion only by hitting against the walls . In the case of a wire suspended in air vacuum the surface of the wire plays the role of the box reflecting the electrons and preventing them from exiting toward the empty space open air. This is because there is an energy to be paid to extract the electron from the medium work function . E.g. ballistic transport can be observed in a metal nanowire this is simply because the wire is of the size of a nanometer 10 math 9 math meters and the mean free path can be bigger than that in a metal http www.jsapi.jsap.or.jp Pdf Number03 CuttingEdge1.pdf External links Category Condensed matter physics Category Charge ... more details

Thus, such stroke may be a complete character or a part of a character. However, in this definition, a complete word written as connected cursive script should also be called a stroke. This is in conflict with the suggested unitary nature of stroke as a relatively simple shape. In the research field of handwriting motor control, the term ballistic stroke is used. It is defined as the trajectory segment between two consecutive minima in the absolute velocity of the pen tip. The time delay between the cortical brain command and a muscle contraction is so large that the 100 millisecond ballistic strokes need to be planned in advance by the brain, as feedback by hand eye coordination requires a much slower movement than is the case in the normal handwriting process.
