Paper Abstract
A process for producing calibration markers directly on the photoconductive surface of video camera tubes has been developed. This process includes the use of either a pulsed Nd:YAG laser, operating at 1.06 μm with a 9.5-ns pulse width (full width at half maximum), or a continuous helium-neon laser. The Nd:YAG laser was constrained to operate in the TEMoo spatial mode by intercavity aperturing. The use of this technology has produced an increase of up to 50 times the accuracy of geometric measurement. This is accomplished by a decrease in geometric distortion and an increase in geometric scaling. The process by which these laser-formed video calibrations are made will be discussed.
