Wang Xinhua, Gao Baoshan. Development of ILS—A Equipment for Machining Invariable Levelling Staff[J]. Editorial Office of Optics and Precision Engineering, 1995,(3): 112-115DOI:
High precision invariable levelling staff is essential equipment in survey
seismology
geology field.Up to mow
there are still no special equipments for machining invariable levelling staff in our coantry.The paper presents the principle and configuration of ILS-A equipment we developed
especially
including the key to the technology for designing and makingdie and the advantages of using the dynamic grating connecting technology. Finally
we putforeward the results detected by using laser interferometer and a discussion.
