Research on improving resolution changed from optical images for bore detecting into video signal wide field-of-view

摘要

With the discussion in the relationship between field of view and resolution in photoelectronic inspection technology, methods and measures are stressed in the paper to output optical images for bore detecting in video frequency with CCD technology in the case of wide field of view and high resolution with the application of nodal point and photoelectronic technology in a optical system, which can solve the engineering problems of wide field of view and high resolution optical image transmission in video frequency with CCD technology in the field of industrial high precision bore inspection.
