As the non diffracting beam has a very small central spot diameter and a long non diffracting distance of transmission, fairly high measuring accuracy can be expected from its application in straightness error measurement. The characteristics and the generating method are studied and the design method of the straightness error measuring system with non diffracting beam is presented. Theoretical analysis and experimental results show that this novel measuring system can meet the requirement for...
