The phrase "angle of illumination" is correct and usable in written English.
It can be used in contexts related to lighting, photography, or optics to describe the specific angle at which light strikes a surface.
Example: "The angle of illumination significantly affects the shadows and highlights in the photograph."
Alternatives: "light angle" or "illumination angle".
Further, during the scanning process, each line of the target scene acquired receives the same angle of illumination, then we can ensure that all spatial points were illuminated under the same conditions.
The shadows cast by great men change shape over time depending on the angle of illumination, diminishing in harsh overhead light or expanding in the glow of distant perspective.
Because the whole system is moving around the Sun once per year, the angle of illumination changes about one degree per day, so that the time from one full moon to the next is 29.531 days, the synodic month, or synodic revolution period of the Moon.
The angle of illumination does not have a large effect on the ion loss from Titan.
Thus, the surface reflection depends on the incident angle of illumination.
Similarly, when pairs of laterally lit spheres were presented and participants were asked to judge which sphere appeared to be more convex, participants chose spheres lit from the left regardless of the angle of illumination.
Under certain angles of illumination weak subdivisions of these structures are apparent, but other angles of illumination reveal alternative demarcations.
Luminance was excluded in the present study, as it is subject to interference from inconsistent angles of illumination and variable distance between the illumination probe and the retinal surface.
In summary, we have shown the applicability of the EJMC approach to understanding the complex 3D structure possessed by articular cartilage by analyzing the PS-OCT data obtained for multiple angles of illumination.
Use a magnifying glass and different angles of illumination to look for unusual characteristics in the rock specimens you gather.
Alignment of the illumination and imaging channels within the probe was accomplished by adjusting the rotation angle of the illumination fiber for maximizing the resulting image intensity.
