Paper Abstract

An optical fiber has been used in a wide area such as in communication system, a view guide for diagnosis, applied optical sensor, etc. In such applications of the optical fiber especially in the sensor, some new sensor may be expected. In this study, possibility of a speckle nose used sensor was discussed. For this, the speckle noise patterns were observed to make clear their characteristics with regard on the miss-match of optic axis and an experimental study was carried out on the influence of edge surface condition, core diameter and distortion. In addition, the speckle noise pattern was measured by using the digital image processing technique, and its characterization was partly made. From these investigations, the possibility of speckle noise used sensor was discussed.
