Paper Abstract

We developed a simulator for the interference fringe type encoder using the Fresnel-Kirchoff diffraction formula. To optimize the design of the encoder's optical system, we used the simulator to analyze the influecne of the following factors: 1) the wavelength band, 2) the radiaont size, and 3) the shape of the diffraction grating surface.
