Paper Abstract

For the test of multi-spectral wide distance optical axis parallelism and structure parallelism for artillery control system, calibrating the central axis parallelism and discrete axis parallelism with the same standards is a problem. Sometimes, it can't be resolved by large-aperture autocollimator lonely. At the same time, the cost is increased greatly. The extend caliber and collimate method is introduced in this paper to receive the centralize axis with appropriate collimator on multi-spectrum, and the discrete axis which is far from the center are guided to the collimator by the special designed extend arm, that will not only make the problem easier, but also ensure the precision. It is shown in practice that the accuracy is higher than 0.01mrad.
