ABSTRACT = {The stress distribution of contact area in engineering structure is complex. Automatic whole-field measurement of photo-elasticity is a feasibility method
to solve the contact problem. However, the problem of isoclinic and isochromatic
interaction is important in phase-shifting techniques of photo-elasticity. The technique named 8-step phase shifting technique is applied to solve the problem of
isoclinic fringe pattern influenced by isochromatic fringe patterns in integer order
and half-integer order. A new automatic technique of stress separation improved
by an application example of contact problem of root gear, which is discussed in
this paper after obtaining the whole-field shearing stress.},
