By using Origin offset gain exponential function method, the traditional continuous zooming system for measuring the focal discretization sampling points was changed into nonlinear exponential points of continuous function. VxWorks continuous zoom and display controlling system was developed, which can efficiently modify the continuous zoom parameters. The issue of lower accuracy that is becoming continuous by traditional continuous zoom discrete sampling points is resolved, it is easy to realize by computer programming. The test analysis indicates that this display control technology is practical and reliable, the fitting credibility is more than 99%,true value proportion is more than the highest quantity to 93.6%,accuracy can meet the demand completely. This technology has been applied to the certain project successfully, and it is a good university and reference for the focal length of continuous zoom optical equipment formulation.
