Abstract :
In order to apply the speckle noise in optical fiber to sensor, a speckle noise pattern due to deformation of an optical fiber was measured by using the digital logic operating technique. As a result, the characterization of the speckle noise pattern could be made possible, when the distortion of the fiber was changed
