diffuse reflection

The reflection of a light ray by a rough surface in which the angle of reflection is not equal to the angle of incidence. As opposed to specular reflection by a smooth surface in which the angle of reflection equals the angle of incidence. Employed in the analytical technique of reflectometry.

This causes the color of specular reflections to be similar to the light's source, while the color of diffuse reflection to be determined by the object's body spectral reflectance.
This phenomenon can be explained by the theory of diffuse reflection, and the sea becomes rougher when the wind speed increases.
Due to requirements of the diffuse reflection technique, all samples were mixed with cesium iodide powder at an approximate ratio of 1 : 5 (zeolite : CsI).
Polymer 4 shows some very weak patterns, and polymer 2 shows only one diffuse reflection peak, indicating that these are amorphous polymers.
As the artificial skin has a rough surface similar to the wrinkles and the skin texture, the pearlescent pigments on the artificial skin show not only specular reflection but also diffuse reflection coming from the roughness of surface.
This third edition contains new chapters on diffuse reflection theories, the calibration and validation of process sensors, and the NIR spectra of gases.
Two regular reflection heads handle transparent and mirror-surface workpieces; three diffuse reflection heads are able to measure black rubber and dark plastic workpieces.
The final simulation of the experiment was done using probabilities of diffuse reflection of 10% and 1%.
His surface isn't completely smooth, so when light rays hit him, they get reflected at all different angles--a process called diffuse reflection. The scattered reflecting makes him look polished and satiny.
The optical sensors use visible and near-infrared spectral reflectance, via a modified diffuse reflection method, to generate the metabolic values for the Hb and Hb[O.sub.2] concentrations obtained from the fingertip.
In the case of a holographic HMI offering an operator one choice, such as a power switch, one potential choice of hardware, for example, might be one diffuse reflection photoelectric sensor emitting infrared having a wavelength of 880 nm, and having the broadest detection range from itself of approximately 50 to 100 mm.
