Saturation Effect

Saturation Effect

 

the decrease in the intensity of a spectral line (an absorption or emission line) with increasing power of the external resonant electromagnetic radiation. The saturation effect is caused by the equalization of the populations of two energy levels between which stimulated transitions take place as a result of resonance radiation. The saturation effect is observed when the power of the resonance radiation reaches the level at which the probability of stimulated transitions owing to the radiation is greater than the probability of relaxation or spontaneous radiative transitions. The saturation effect limits the power that can be generated by a laser.

Every technique has its own strengths and weaknesses, and the saturation effect above 50 moths per trap can be remedied by changing the trap bottoms more frequently.
It is well known that influence of sensor saturation effect increases as distance from the target to the sensor decreases.
To account for a possible saturation effect with fireworks, where fans are not as interested in attending games with fireworks as their frequency increases, fireworks are included in the model in three ways.
These timelines have lengthened in recent years due to a pipeline saturation effect and the presence of judicial hurdles in some states.
To quantify the saturation effect on sand resistance to liquefaction, Yang (2002) used normalized cyclic resistance (RLn), which is the ratio between resistance to liquefaction of a partially saturated sand (CR) to that of a saturated sand.
In this case we use the solution described in this paper, use the saturation effect.
However, they also noted that the interaction between stress and pollution was no longer evident beyond a certain range of exposure, a phenomenon they refer to as the saturation effect.
Dazzling with high power continuous or quasi-continuous pulsed laser causes the sensory systems to functional failure or a delayed reversible saturation effect on the detector array as shown in Figure (9-14).
In this case, we're going to split the sharpening into two layers--one for lighten halos and another for darken halos--so we'll use another method to eliminate the saturation effect of the sharpening.
It also has an enhanced anticollision protocol, which performs without saturation effect.
But there is optimism that these problems can be overcome quickly with a mix of new hardware like next generation CMOS high dynamic range sensors that limit the saturation effect of sunlight and allow cameras to "see" the eyes more clearly, as well as through further algorithm requirements.
If more storms roll in this weekend, Oakmont could be sorely tested, since, as Frederick noted, the course's considerable draining capacity could be overwhelmed by the saturation effect.
