Paper Abstract

This paper presents an improvement approach to realize tracking on smooth glass surface based on subjective speckle. The scattering mechanism on glass surface is analyzed and the affection on tracking precise and range for tracking with subjective speckle is researched. The speckle captured by CCD just from the upper surface of the glass is achieved by grazing incidence of the laser beam and the noise mixed with the signal is eliminated by a barrier above the surface. Based on the apparatus of subjective speckle tracking, the speckle contrast is improved from 0.25 to 1.25 by non-Gauss effect and the range of the tracking has been increased from 200 μm to 400 μm compared with the objective speckle method on the same condition.
