ABSTRACT:
A electronic system develops a rotating raster scan in synchronism with a tating image enabling a stationary image sensor to generate video signals for producing an erect, non-rotating image at a remote location. Sine and cosine signals are synchronously developed with the rotation of the image as a function of the instantaneous angle of the rotation. The sine and cosine signals are combined with linear vertical and horizontal sawtooth deflection signals and applied to the deflection means of the stationary image sensor to produce an erect, non-rotating video image on the face of a remote cathode ray tube display.
