Experimental Study of Contrast Utilizing a Vidicon.

Abstract

A commercial multi-purpose closed circuit television camera system with a vidicon image tube was studied to determine its capability for measurement of contrast and visibility. A single line of the scan from the camera video output was extracted and examined with an oscilloscope. A derivation of system response was made and a comparison performed with laboratory data. Calibration of the field of view, for one particular television pick-up tube, revealed nonuniformities making resolution of 2 percent contrast difficult. Useful resolution results are expected with improvement of the pick-up tube or with employment of digital processing techniques. (Author)
