This report propose a method to improve the position measurement accuracy of encoded laser beam scanning type signal field. This signal field system is effective in measurement at small semi-opened field. However, the conventional position measured value is discrete, because this measurement system used M-sequence code consist of 1 and 0. In this research, we proposed to make conventional discrete value linear by instrumentation of phase shift value on observed signal. First, the principle of encoded laser beam scanning type signal field is referred, and position measurement accuracy is mentioned. Next, a method of high resolution measurement system is proposed, and effect of this method is confirmed by a experiment using the system we designed.
