  • Patent number: 10571259
    Abstract: An optical detecting apparatus for detecting a degree of freedom error of a spindle and has a standard bar and a sensor module, and is assembled between a spindle and a rotating platform of a powered machinery. The standard bar has a rod lens and a reflection face. The sensor module has two detecting groups, an oblique laser head, and a reflected spot displacement sensor. Each detecting group emits a laser light through the rod lens along the X-axis and the Y-axis of the powered machinery. The oblique laser head emits an oblique laser light to the reflected spot displacement sensor. When the spindle of the powered machinery generates errors after rotating, the sensor module receives the changes of the laser lights to obtain the displacement change signals of the standard bar for a calculation unit to detect the errors between the spindle and the rotating platform.
