Abstract

As the optoelectronic aiming and orientation of an optoelectronic tracker effect directly the overall measurement accuracy and operational performance of instruments

this paper proposes an improved design scheme. Firstly

the optoelectronic aiming and orientation control technology of the laser tracker was analyzed

and a systemic technological scheme for optoelectronic detection and aiming

signal regulate acquisition

digital signal processing and intelligent tracking servo was proposed. The key components in the system were selected

and the detection optical path and signal processing circuit were designed by using a cube-corner prism and a Position Sensing Detector(PSD) as the photoelectric detecting core. Then

a system prototype was developed and a standard test platform for target displacement was established to test the detecting signals of photoelectronic aiming system in the prototype. The tested results demonstrate that the proposed system performance index has achieved

in which the static precision of the position measurement is up to 6 μm

and the stochastic dynamic tracking measurement speed is greater than 1 m/s. It shows that the proposed method improves orientation accuracy and tracking effect of the laser tracker and provides reference for development of measurement instruments with high accuracy and large-scale fields.
