A Greninger chart can be used to interpret the back reflection Laue photograph.
2.
The Greninger chart is a simple trigonometric tool to determine " g " and " d " for a fixed sample-to-film distance . ( If one uses a 2-d detector the problem of determining " g " and " d " could be solved mathematically using the equations which generate the Greninger chart ) A new chart must be generated for different sample to detector distances . ( 2 " s " is 2 " q " for the diffraction peak and tan " m " is " x " / " y " for the Cartesian coordinates of the diffraction peak . ) The Greninger chart gives directly the two angles needed to plot poles on the Wulff net.
