Paper Abstract

In this paper, a novel target tracking approach is presented. A scanning mirror has been applied to modulate object and background signal periodically. The object position can be derived by a formula composed of 1st-order and 2nd-order harmonic components obtained form output signals via Fourier transform. Because the field of view of optical system is very small, the radiation from background collected by four cells of quadrant detector doesn't change in short time. The radiation of background can be suppressed. The result of experiment shows that this tracking approach has a high precision without the influence of the radiation from background and the energy distribution of image spot.
