In our research, we present a novel method for absolute angle positioning by non-distortion laser speckles imaging technique. On the surface of a circular plate, we can use a non-distortion speckles imaging device to get the nondistortion image accor

The accuracy of precision measurement is an essential requirement for precision positioning. This paper presents a new precision measurement method by combining the uniqueness analysis of laser speckle patterns (LSPs) and the template matching algori

Laser speckles have been used in measurement techniques, since they were discovered to be correlated with the displacement of the light source. This paper presents a robust technique of analyzing and locating laser speckle patterns (LSPs) for a proto

This paper presents a novel personal identification method by extracting unique object features from optical speckle patterns using the SIFT (Scale Invariant Feature Transform) algorithm. Accurate identification is achieved by developing an invariant

We used the invariance of moving laser speckle patterns to develop a finger-controlled navigation system. Laser speckle images were captured using a commercially available image sensor. The relationships between template image size, available movemen
