Measurement of Distribution of Blood-flow Change in Exposed Cortex by Laser Speckle Flowgraphy
Laser Speckle Blood flow Imaging
2009/6/2
The change in the cortical blood flow of guinea pigs during auditory stimulation is measured by laser speckle flowgraphy (LSFG). Accuracy of LSFG depends on the number of the frames for the blood flow...
Two-photon speckle as a probe of multi-dimensional entanglement
Two-photon speckle multi-dimensional entanglement
2010/4/8
We calculate the statistical distribution P_2(I_2) of the speckle pattern produced by a photon pair current I_2 transmitted through a random medium, and compare with the single-photon speckle distribu...
