Specific embodiment principle as shown in Figure 3, light source be formed by incident ray angle be β, measuring device bottom with
Vertical range L between light source0, the horizontal distance L of thin-walled root and the reflection outermost edge of optical receiver1.If thin-walled is vertically without change
Shape, incidence angle and angle of reflection are γ1, incident ray is fallen in through thin-walled reflection to be reflected on optical receiver.And in practice, thin-walled deformation
Tilt angle is α, and at this moment, the practical angle of reflection that incident ray is reflected through thin-walled is γ, and practical reflected ray is in reflection optical receiver
On drop point be O.Drop point O is L at a distance from measuring device2, it is L at a distance from ideally-reflecting line drop point site.Qualitatively
Analysis, as thin-walled inclination angle alpha changes, the position of practical reflected ray drop point O can change, therewith, distance L and L2Also can change
Become.It can be by establishing inclination angle alpha and distance L2Between relationship, acquire thin-walled deformation tilt angle [alpha].Certain thin-walled deformation
