Our unbelievable story began when we received an e-mail from the NASA. The request from the National Aeronautics and Space Administration was crystal clear – to create a display that would be photographed by high-speed cameras verifying !!!( the reliability of the timing)!!!!. For many years, the NASA had used old digitrons with an accuracy of 0.001 seconds. Our challenge was even greater. To increase the accuracy to 0.0001 seconds.
