diffuse density
The logarithm of the reciprocal of diffuse transmittance. Diffuse density results when a sample is diffusely illuminated.
diffuse illumination
Light emitted by one or more sources and characterized by a high degree of scatter.
diffuse modulation transfer function
Modulation transfer function of an optical element when used for transporting images from a lambertian source such as phosphors.
diffuse reflectance
Ratio of diffusely reflected flux to incident flux.
diffuse reflectance spectroscopy
Diffuse reflectance spectroscopy (DRS) is a nondestructive analytical technique used to investigate the optical properties of materials, particularly in the field of spectroscopy. Unlike traditional...
diffuse reflection
Nonspecular reflection from a rough surface.
diffuse reflector
A reflecting surface that scatters radiation that is incident on it, thus producing diffuse reflection.
diffuse sensing mode
Use of a photoelectric receiver to sense an object's presence by detecting a small amount of the emitter's light that is diffusely reflected by the object.
diffuse transmission
Transmission accompanied by diffusion or scatter to the extent that there is no regular or direct transmission.
diffuse transmittance
The ratio of diffusely transmitted flux to incident flux.
diffuse-cutting filter
A color filter that is designed to gradually increase or decrease its absorption with wavelength.
diffuser
An optical diffuser is an optical component or material designed to scatter or diffuse light that passes through it. It is used to create a more even or uniform illumination, reduce glare, or soften...
double diffuse density
Measurement derived from calculation when incident flux of a negative is entirely diffuse and all radiation transmissions are included.
diffusing screen
In printing, a translucent screen used with lenses to provide an even distribution of diffused light.
diffusion (light)
->
light diffusion
Light diffusion refers to the process by which light is scattered or spread out in various directions as it interacts with a medium or material. Unlike direct transmission through a transparent...
