The lens creates a speckle pattern
that can be scanned on the object.
They used a miniature high-speed camera to record the fluctuating speckle pattern
For these micro-thermal gradients to be effective the pulse repetition rate needs to be slow enough to allow a complete relaxation of these gradients (for micron sized 'hot spots' this relaxation time is in the millisecond range) prior to the generation of a novel speckle pattern
generated micro-thermal pattern.
As an example, Figure 5(a) shows the speckle pattern
(field intensity) by a one-dimensional perfectly conducting rough surface.
In most cases, they ended up taking three or four birds to the taxidermist, unable to decide which speckle pattern
they liked best.
He therefore switched to electronic speckle pattern
interferometry, a computer-based method.
This means that the primary speckle pattern
is compared to the pattern on the reference surface which enables the depth calculation throughput crosscorrelation or decorrelation (Um et al.
Based on the prepared speckle pattern
of the specimen surface or simply the natural surface characteristics, the size of the subset and corresponding ROI are selected, as shown in Fig.
One of her most popular discoveries was her speckle pattern
Development of the electronic speckle pattern
interferometry and mark tracking techniques for the elastic properties of polymers and coated polymers.
High speed changes in speckle pattern
images are observed from IRFPA.
The optical principle, governing the laser speckle pattern
shift technique to determine strain, was originally devised by Yamaguchi  and later improved by several authors [2-5].
4-6) This behavior of the speckle pattern
can also be observed in nonbiological industrial processes, including the drying of paint, corrosion, and heat exchange.
Holographic interferometry and electronic speckle pattern
interferometry are similar.
