0 a very small mark of a different colour from the area around it, usually found with a large number of other marks of the same type:
At this stage, these and other concepts are still being developed to increase the level of speckle smoothness for direct drive.
From the transmission geometry of a small-angle experiment it is obvious that the transverse coherence length is the key factor that determines speckle.
In these experiments, however, the average power in a speckle was of the order of 3% of the critical power for self-focusing.
The instantaneous focal spot intensity is a highly nonuniform speckle.
The target then integrates over a large number of uncorrelated speckle patterns and therefore "experiences" smoother irradiation.
The wide divergence laser beam eliminates the speckle patterns caused by the phase plates.
The very first section features a typically multi-layered texture with helter-skeltering violin scales speckled with pizzicato strings, brass and keyboards.
The final chapter is on fundamental limits in photoelectric detection of light, and different kinds of interferometry, including speckle interferometry, are discussed in this context.
