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.
