The desired outcomes included reduced specular reflection (glare), increased illumination beam pattern uniformity, and reduced electrical power budget.
Undeterred by glaring searchlight illumination and withering blasts of hostile weapons, he proceeded through hazardous waters, located the designated beach and directed the assault boat wave.
Light pollution comes in many forms, including sky glow, light trespass, glare, and over illumination.
Designing spaces that are able to balance illumination, glare and solar gains over a year is a real challenge, yet a problem faced every day by building designers.
Moreover, when using traditional tools, designers are unable to directly experience some lighting phenomena that may affect the visual perception of the occupants, e.g., brightness, darkness, glare, or insufficient illumination.
However, improperly-placed lighting can actually cause problems due to screen glare or over-illumination of the eye, which causes the pupil to constrict and makes the screen harder to see.
The amount of veiling luminance depends on the illumination of glare source, the age of the observer, and angle of the glare source [1, 15] as shown in Eq. (4): {L}_v=frac{ktimes {E}_{glare}}{theta^n} (4).
Veiling glare is a global illumination effect that arises from multiple scattering of light inside the camera's optics, body, and sensor.
In the equations, L v is veiling luminance, E glare refers to the illumination of glare source to the eye in lux, θ is the angle of the glare source, angle between the line of sight and the centre of the glare source, in degrees.
That manuscript, "Illumination and Night Glare: the Unfinished Autobiography of Carson McCullers," was published late last year.
