It represents the logarithm with base 10 of the power transmission factor of an optical attenuator. For instance, an optical density of […]
Source: Wikipedia The Fascinating World of Speckle Patterns Speckle patterns are random granular patterns that occur when a coherent light beam, such as from a laser, is diffusely reflected on a surface with a rough structure. These patterns result from the interference of various reflected portions of the incident beam with random optical phases. Understanding

However, this method is not very efficient as most of the light is lost at the modulator, and the pulse duration
