Development of ILS—A Equipment for Machining Invariable Levelling Staff
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.
Research on an auxiliary assembly and calibration system based on the analysis of the spatial modulation function features of the light field time-grid
Improving LED luminescence properties by using Ag/P-GaN double grating
Mechanism of frictional chatter during mechanical ruling grating
Angle displacement measurement device for fast-steering mirror in vehicular laser system
Accuracy calibration of chip mounter alignment system based on grating
