We propose a new arrangement of LEDs and detector and a digital filter for our proximity sensor to realize multiple points sensing of an object surface within 1ms. The accuracy and calculation time were verified by simulations. From these results, the proposed method enables a higher density arrangement than the conventional arrangement. The processing circuit can be downsized by replacing a conventional analog synchronous detection circuit with the proposed digital filter.
