Automatic Recording of Object Motion by the Speckle Method in the Terahertz Range
Using a microbolometer detector array, we recorded real-time images of metallic and dielectric objects illuminated by monochromatic terahertz radiation, including those hidden behind an opaque barrier. It is shown that the characteristics of movement of rough objects dynamic can be retrieved from the dynamics of the speckle structure of their images in the terahertz range. An automatic processing algorithm for terahertz videos with recording of moving objects was developed and software implemented.
