ABSTRACT:
Electro-optical gaging system has an electronic camera which develops a raw camera pulse having a width that approximates the dimension between edges of an object imaged on the camera. A camera pulse processor employs edge detecting techniques using raw pulse differentiators, threshold detectors, zero cross-over detectors, and an autocorrelator to eliminate differentiator-generated noise. This processor produces a precise output pulse that accurately defines the object edge dimension and may be used to drive A/D measuring and/or converting circuits.
