技術說明

一種旋轉角度量測系統，設有一光源、一感測組及一訊號處理組，該光源為一雷射光束，該感測組接收該光源且設有一分光鏡、一聚焦透鏡與一楔形鏡，該分光鏡將該光源的雷射光束均分為兩道光束，其中一光束垂直穿過聚焦透鏡的中心點，該楔形鏡係設於一待測物的旋轉軸上並接收經聚焦透鏡聚焦的雷射光束且反射回該分光鏡，該訊號處理組係用以接收該感測組經反射的雷射光束且設有一二維位置靈敏檢測器及一訊號處理電路，而該訊號處理電路係與該二維位置靈敏檢測器相電連接，進而提供一方便架設且可避免因偏心而造成量測誤差的旋轉角度量測系統者。 For the precision measurement of rotary indexing angles, a measurement system has been proposed that consists of: a light source, a detector module and a signal processing module. A laser beam serves as the light source. The detector module which includes a beam splitter, a focus lens and a wedge mirror will detect the light beam. The beam is divided into two beams by the beam splitter. One of them propagates through the center of the focus lens. The wedge mirror is fixed on the rotary axis of the object. The laser beam travels through the focus lens and then is reflected by the wedge mirror. The reflected beam transmits through the focus lens again and also the beam splitter. The reflected laser beam is detected by the signal processing module. In the module there are a 2D position sensitive detector (PSD) and a signal processing circuit.
