Specifically, in the preferred embodiment, the work piece 2 is illustrated by the spindle head of the processing machine. Of course, the work #2 may also be a lathe device or other device that causes displacement to cause an angular change. Referring to Figures 1 and 3, the combined angle measuring system of the present invention comprises a light source device 3, an interference generating device 4, a light steering device 5, and a light source device 3 capable of generating a direction toward the first direction X. Light beam 31. In the preferred embodiment, the light source device 3 is implemented by laser irradiation and the first beam 31$ is equivalent to the laser light. However, other directional light can also achieve the same effect in 201226847. Therefore, it should not be preferred. The content disclosed in the embodiments is limited. The interference generating device 4 includes a linear optical path μ, and a beam splitter group 42 and a mirror group 43 respectively disposed at opposite ends of the optical path 41. In the preferred embodiment, the beam splitter group 42 has two spectroscopic mirrors 421 arranged in parallel. Of course, the beam splitter group 42 can also use only one beam splitter 421 'the other beam splitter 421 is used to split the beam. The mirror 421 is replaced by a corner mirror that is spaced apart. In the preferred embodiment, the mirror set 43 has two mirrors 43i that are parallel and disposed corresponding to the dichroic mirror 421. Referring to Figures 3 and 4', the light steering device 5 is detachably coupled to the interference generating device 4. In the preferred embodiment, the light redirecting device 5 has a fifth turn 51 that changes the direction of travel of the beam 31. The five turns 51 have two oppositely disposed reflecting surfaces 511, a connecting surface 512 connecting one end of the reflecting surface 511, and two outer surfaces 513 connected to each other and connected to the other end of the reflecting surface 511.
