| Abstract: | Two-dimensional galvanometric scanner is an important device used in active laser detection system to realized the scan of a certain view field. Aiming at the defect of galvanometric scanner′s non-uniform scanning, the principle of two-dimensional galvanometric scanner is discussed, the full-cover condition of laser spots is analyzed and the formula between uniform space and driving signal is deduced. The software implementation of uniform scanning is presented with control circuit of single-chip and the time-series of scanning circuit is analyzed. This method can be useful for improving detecting efficiency of active laser detection system for its simple process and easy realization of laser spots′ uniform sampling. |
| Keywords: | active laser detection galvanometric scanner uniform scanning |
