Web7. aug 1999 · Spatial filtering is a process by which we can alter properties of an optical image by selectively removing certain spatial frequencies that make up an object, for example, filtering video data received from satellite and space probes, or removal of raster from a television picture or scanned image. WebPhysics One of the most interesting and exciting applications of lasers lies in the fields of spatial frequency filtering and holography. In this chapter, we briefly outline the principle behind spatial frequency filtering and holography and discuss their applications. View via Publisher Save to Library Create Alert Cite References
