Based on laser-scanned inspecting technology, grating
displacement measuring technology, close-loop servo control
technology, computer real-time control and data processing
technology, a bullet corre dimension optoelectronic comprehensive
measuring system is presented, which is used to non-contact
measurement of dimensions for the bullet core part of
armor-piercing bullet. In this paper, the constitution and overall
structure of the system are described. The measuring principle and
method of the radial dimension, axial dimension and pitch are
theoretically studied. The laser-scanned inspecting system, grating
displacement measuring system, close-loop servo control system ang
its dynamic characteristics as well as computer control system are
discussed in detail. The measuring errors of the system are
theoretically analysized by experiments. The experimental results
has shown that the system can meet the measuring requirement of the
dimensions for bullet core part.
