Abstract

In this paper, the measurement error of a diffusereflection-type laser displacement sensor is analyzed for profile measurement. Multi-reflection error is predicted by a simple-beam-tracking simulation. Based on the simulation results, the measurement range of a laser displacement sensor is tuned, and multireflection error is reduced. Then, measurement errors in the experimental measurement of a small die are evaluated.
