In this research, I performed the conceptual design of the femtosecond laser lan using a femtosecond comb range sensor. I verified the feasibility (measurement accuracy, measuring time, cost, and environmental conditions) of the proposed system. From the feasibility analysis, I have checked the practicality of the proposal system. Moreover, there was a problem in the pulse interval of femtosecond laser. About this, I conducted the experiment which shortens a pulse interval using fiber etalon, and checked the validity of the system. Furthermore, I performed the basic research of a scanner and a CCD camera for three dimensional measurement, and checked the possibility of the system.From the above results of the research, I was able to realize the validity of the proposed femtosecond laser lan system, and the possibility of industrial application.

在本研究中，我使用一飞秒梳状距离感测器进行飞秒雷射网路的概念设计。我验证了该系统的可行性（测量精度，测量时间，成本和环境条件）。从可行性分析的角度，对该建议制度的实用性进行了检验。此外，飞秒激光的脉冲间隔也存在问题。为此，我进行了使用光纤标准具缩短脉冲间隔的实验，并验证了系统的有效性。此外，我还对用于三维测量的扫描仪和CCD摄像机进行了基础研究，并对系统的可行性进行了验证，从以上研究结果中，我能够认识到所提出的飞秒激光扫描系统的有效性，以及工业应用的可能性。
