Astronomical Photometry: A Guide
1.2.1 General definitions We now discuss four fundamental quantities in
radiometry: radiant flux, radiant intensity, irradiance and radiance. The
corresponding quantities in photometry are distinguished by the root "lumi-" in
place of "radi-": ...

Optical Coherence and Quantum Optics
5.10 The polar diagram (a) illustrating the angular distribution /"'(s, v)/ on(v) [Eq. (
5.3-55)] of the normalized radiant intensity, generated by a Bessel-correlated,
planar, secondary, quasi-homogeneous source. Figure (b) shows the behavior of
...
Leonard Mandel, Emil Wolf, 1995

Principles of Naval Weapon Systems
In an effort to quantify the power emitted by a source, a distinction is made
between types of sources, and separate terms are used to describe the radiation
from each.x"1 Radiant Intensity— I Radiant intensity is an expression of the
brilliance ...

Handbook of Optoelectronics (Two-Volume Set)
A2.2.3.2 Radiant intensity and luminous intensity Radiant intensity (Ie) or
luminous intensity (Iv) is the radiant flux (luminous flux) from a point source
emitted per unit solid angle in a given direction, as defined by dF dV I 1⁄4 ðA2:2:
4Þ where dF ...

Infrared Technology Fundamentals, Second Edition,
SPECTRAL RADIANT INTENSITY The spectral radiant intensity is a property of a
source, and is defined with respect to a given wavelength X of the radiation, a
given point Q, and given direction C. The spectral radiant intensity of a source in
a ...

Algae: Anatomy, Biochemistry, and Biotechnology, Second Edition
Radiant intensity is measured in watts per steradian (W sr −1). Combining the
definitions of radiance (Equation 4.13) and radiant intensity (Equation 4.17) gives
us an alternative definition of radiance: L I A = d d q qcos , (4.20) where dIθ is the
...

Shock Waves: 26th International Symposium on Shock Waves, ...
Figure 4 shows that the apparent radiant intensity (ARI - watts/sr/cm ) is higher for
a large versus a small charge at all times throughout the burn. The peak intensity
ratio is 1.2, while the total intensity ratio is 2.37. The peak gray body apparent ...

The Mechatronics Handbook, Second Edition - 2 Volume Set
The corresponding photometric quantity is illuminance, measured in 1m irf 2(lux).
Radiant intensity (/) is a measure of a point source's ability to illuminate a surface,
which decreases as the square of the distance d to the surface. It is measured ...
Virtually all the photons would stream off in a single direction and the eye would
see nothing unless the pupil were positioned to intercept the reflected beam. The
radiant intensity, I e , is the radiant power emitted in a particular direction into the
...
