This is a report on optical design of Laser transmitter and receiver for Ruggedized Total Station for military-use. Using a high efficiency Laser Diode causes problems such as elliptical beam and Astigmatism. This experiment involves design and analysis on how to minimize beam divergence and how to resolve the problem that occurs on duplex optical receiver for near field measurement. In order to make it available for military-use, we performed an experiment with optimized design using optical component that minimized the performance alteration in multiple conditions such as temperature, impact and vibration. In addition, we secured a technology to apply this on buildings, spatial geodesy, and targeting for military use. At the same time, we have also secured a technical base for practical application of next stage technical development such as three dimensional spatial geodesy equipment.
