Zhang, X B, Lu, H, Jiang, Xiang and Li, Z. (2005) A straightness error measurement method matched new generation GPS. Journal of Physics: conference series, 13. pp. 402-405. ISSN 1742-6596Metadata only available from this repository.
The axis of the non-diffracting beam produced by an axicon is very stable and can be adopted as the datum line to measure the spatial straightness error in continuous working distance, which may be short, medium or long. Though combining the non-diffracting beam datum-line with LVDT displace detector, a new straightness error measurement method is developed. Because the non-diffracting beam datum-line amends the straightness error gauged by LVDT, the straightness error is reliable and this method is matchs new generation GPS.
