A double-crystal monochromator is a key optical part of synchrotron radiation beamlines
and the effect of the first crystal attitude error on exit beam direction is complex.In this paper
a spatial diffraction model of synchrotron radiation on the face of the first crystal was established.The effect of the first crystal attitude error on the exit beam direction was obtained.At different Bragg angles
the position of facula in a fluorescent target was measured
and the pitch
roll and yaw errors was derived.The method has been applied in adjusting the first crystal attitude mechanism.
