A method for precision measurement of invariable relative height in double crystal monochromator
the principle of double crystal monochromator in beam lines of synchrotron radiation facilities is introduced
and the technique of invariable relative height in double crystal monochromator is used to keep the height of the beam from the monochromator.A CCD imaging system and an image processing system are used for off-line test.The precision is analyzed.The results show that the measurement precision of relative beam height is primary factor.The precision of the system reaches 4.9 μm
