granulaatsioonivõnkumine

Granulatsioonivõnkumine refers to the random fluctuations in the number of photons detected in a light source. This phenomenon is a fundamental aspect of quantum mechanics, illustrating that light, while often treated as a continuous wave, also behaves as a stream of discrete particles called photons.

The intensity of a light source determines the average number of photons emitted per unit time. However, due to the probabilistic nature of photon emission, the actual number of photons detected in any given interval will deviate from this average. These deviations are the granulatsioonivõnkumine. The magnitude of these fluctuations is inversely proportional to the square root of the average number of photons. This means that at low light intensities, the relative fluctuations are more significant, while at high light intensities, they become much smaller and less noticeable.

Granulatsioonivõnkumine is a fundamental source of noise in optical detection systems. Understanding and quantifying these fluctuations is crucial in fields like quantum optics, where experiments often rely on detecting single photons or very faint light signals. Techniques such as photon counting are used to measure these discrete events and study the statistical properties of light. The phenomenon is also relevant in astronomical observations and any application where light intensity measurements are critical and subject to quantum uncertainty.
