Method for spatial movement detection of reflecting body or diffuser by means of holograms, involves producing surface holographically, which is to be detected

摘要

The method involves producing the surface holographically, which is to be detected. Three-dimensional light patterns during movement by this pattern produce an analog for pattern intensity characteristic change of the scattering intensity. Conclusions are possible over different physical dimension of the movement such as place, speed and direction of the object from the position of the three-dimensional pattern and the temporal process of the backscattering intensity.
