Abstract
A synthetic aperture video photometer system wherein the synthetic aperture is established by an apparatus which senses video output from an interactively determined portion of an image-producing display, develops an electrical signal from the sensed video output and digitizes the electrical signal to develop an M by N array of digital pixel values, which correspond only to the interactively determined portion of the display. The apparatus then analyzes the pixel values for the automated inspection of the display. The automated inspection may include luminance, jitter and line width measurements. The synthetic aperture video photometer system provides a photo detector system which utilizes a synthetic aperture to eliminate the use of an aperture mask. The synthetic aperture video photometer system also provides a photo detector system wherein the synthetic aperture may be adjusted to eliminate undesirable video output of a test pattern which would saturate the photo detector.
