Research on Zero-Coding Optimization

It is difficulty to get the most reasonable project artificially when the number of the encoding sequences is bigger so a method of computer simulation is introduced. Base on the mathematics model of the zero-coding, the reciprocal of the contrast D, the general number of bright lines, the general number of reticles, and the influence on the zero-coding due to differ photoelectric devices are considered. The project of zero-coding sequences with higher contrast and light-passing efficiency or higher signal-to-noise ratio is achieved via the optimized non-symmetric encoding.
