Paper Abstract

A dynamic auto-collimation system for inspecting the performances of optical tracking devices is proposed and analyzed in the paper, which includes a simulation of a moving target and the gimbaled mirror embedded in the optical path of auto-collimation to construct a close loop of measurement. In this system, the gimbaled mirror tracks the movement of simulation target and the auto-collimation gives the tracking deviation and feedback to the system. Static pointing accuracy, response to step movement and dynamic tracking performance of the tracking device under test were measured for the two axes of gimbaled mirror. The researched result shows that the method is effective in indoor inspection of static and dynamic performances of optical tracking devices constituting of gimbaled mirrors and other large angle beam steering devices.
