Abstract:	本文結合雷射干涉儀、視覺系統以及二維精密移動平台，發展一工作範圍為18 mm × 18 mm 的高精度視覺檢測平台系統。本文將視覺系統置於三次元量床（CMM）之Z 軸上，並於CMM 床台上架設雷射、分光鏡與反射鏡組以及X-Y 移動平台。經由移動平台可移動待測物件的兩特徵點(如角落)至相機可視範圍，再分別擷取含有此二特徵點的兩張影像。藉由雷射干涉儀量取平台移動之位移量，以及於同一影像平面下求取兩特徵點相對距離，即可求得此兩特徵點之實際距離。本文以所發展的二維雷射視覺量測系統，量取幾個Olympus In the paper laser interferometer, vision system and a two-dimensional precision translation stage are used to develop a high precision measuring station with a working range of 18 mm × 18 mm. The vision system is installed at the Z-axis of a coordinate m
