Automatic Measuring System of Alignment Error Based on Laser Collimator Technique

The measuring principle of alignment error based on laser collimator technique was introduced. The laser structure, the signal processing circuits and the data acquisition were proposed in detail. Two kinds of straightness measuring and evaluating methods were synthetically applied, so the measuring and evaluating software of linearity error can be applied to many measuring instruments such as laser collimator,electron leveler and so on. Using the two ideal contain consult straight line which satisfies the principle of the least condition, the calculated date of straight line error has features of high precision and high speed , the experiment shows that the system provides excellent stability and reliability, and it can be popularized easily.
