This paper describes simulation results for performance improvement of the optical sensor. Mathematical models for measuring mechanism in direction of X, Y and Z axis are presented. Based on the models, variances of sensitivity were investigated according to both parameter x_(0) in X, Y and Z direction and x in Y and Z direction. As the results, it was found that the less x_(0), the higher sensitivity in the x direction, In addition, the sensitivities in the Y and Z direction are increased when x_(0) is decreased, and x is increased. This paper shows that the optimum values of x_(0) and x can be selected for maximum sensitivity.

In this paper, the optical measuring method to detect a distance between a tool and a workpiece is described. This method is based on the intensity modulation and the corresponding measurement system consisted of a laserdiode as an optical source and a photodiode as an optical detector. This paper especially proposes that suitable beam shape radiated from the optical source is line shape due to its nearly constant profile of intensity distribution in direction of line, and the two-element photo diode is useful to detect the machine origin a machine tool.
