Progressive power lens measurement by low coherence speckle interferometry
(2013-07-01)
This work proposes a method for dioptric power mapping of progressive lenses through dual wavelength, low-coherence digital speckle pattern interferometry. Lens characterization finds several applications and is extremely ...

Roughness measurement of paper using speckle
(2011-09-02)
We present a method of measure of the roughness of the paper based on the analysis of a speckle pattern on the surface. Images of speckle over the surface of paper are captured by means of a simple configuration using a ...
