angle of incidence

[′aŋ·gəl əv ′in·sə·dəns]
(optics)
The angle formed by a ray arriving at a surface and the perpendicular to that surface at the point of arrival. Also known as incidence angle.

Angle of incidence

In terms of solar energy, the angle that the sun’s rays make with an imaginary line perpendicular to a surface. The angle of incidence determines the intensity of the energy that any surface experiences.

Angle of incidence is the angle between the fuselage reference line and the wing chord.

Incident rays on a surface. Two ways of measuring angle of incidence.
i. The acute angle formed between the chord line of an airfoil and the longitudinal axis of the aircraft on which it is mounted. This is the angle at which the airfoil is attached to an aircraft fuselage when the aircraft is in rigging position. Unlike the angle of attack, the angle of incidence is a fixed entity.
ii. The angle at which a ray of energy impinges upon a surface, usually measured between the direction of propagation of the energy and the perpendicular to the surface at the point of impingement, or incidence. In some cases involving radio waves, the angle of incidence is measured relative to the surface.

The wind tunnel setup also involved the installation of the temporary turn-table (See Figure 2) for varying the wind incident angle.
Second, the matted plate and the optical fiber have close (similar) BTDFs near the zero incident angle.
Since a standard for the measurement of pearlescent pigments is under development by an ASTM committee, ASTM-E2194, which recommends 15 [degrees], 45 [degrees], and 110 [degrees] from specular angle at incident angle 45 [degrees] for metal flake, (17) is one of the candidates fro the multiangle measurement.
Because much scatter occurred at the surface when we used the diffuse sensor, the reflected light intensity was not very sensitive to the incident angle.
Also important for the FSS design is the maximum incident angle for both reflection and transmission.
The incident angle range of 30-90[degrees] was selected to reduce secondary effects that may be induced by minor surface roughness or instrumental anomalies (3), (5) This angular range yielded the most consistently linear behavior in plots according to Eq.
The quantity of absorbed energy trough Fresnel reflection depends on the incident angle of the radiation over the metal bath.
The sample rotation stage and the detector ring position determine the incident angle of the beam on the sample and the viewing angle of the detector.
It is also comprised of a second spacer layer which does not provide significant incident angle dependent variable path-length difference, the spacer layer being selected from the group consisting of silicon dioxide, magnesium fluoride, magnesium oxide, magnesium hydroxide, aluminum oxide, aluminum hydroxide, titanium oxide, titanium hydroxide and iron oxide.
SolarPrint's technology, which mimics photosynthesis, is tuned to harness ambient or diffused light regardless of the incident angle, enabling it to produce a higher power output than other PV technologies.
