Wikipedia

  1. fluence

    In radiometry, radiant exposure or fluence is the radiant energy received by a surface per unit area, or equivalently the irradiance of a surface, integrated over time of irradiation, and spectral exposure is the radiant exposure per unit frequency or wavelength, depending on whether the spectrum is taken as a function of frequency or of wavelength. The SI unit of radiant exposure is the joule per square metre (J/m2), while that of spectral exposure in frequency is the joule per square metre per hertz (J⋅m−2⋅Hz−1) and that of spectral exposure in wavelength is the joule per square metre per metre (J/m3)—commonly the joule per square metre per nanometre (J⋅m−2⋅nm−1).

  1. Fluence

    In physics, fluence is the flux integrated over time. For particles, it is defined as the total number of particles that intersect a unit area in a specific time interval of interest, and has units of m–2. Fluence can also be used to describe the energy delivered per unit area, in which case it has units of J/m². It is considered one of the fundamental units in dosimetry. In light based medicine and dentistry, fluence, which may be more properly referred to as radiant exposure, is a measurement of energy over area. The area is usually the spot size of the light device. It has two equivalent definitions: 1. Suppose N particles pass through an area A. The particle fluence for the area A is defined as: In the limit of infinitesimal area, this is: 2. Imagine an infinitesimal volume dV with particles passing through it. The particle fluence can be defined as where is the sum of all the path lengths of the particles that traverse the volume. These definitions are equivalent as can be seen by multiplying the first definition by where dx is the typical path length of a particle in the volume. The numerator then gives the total path length traced out by the dN particles in the volume while the denominator gives the volume dV.
