In order to obtain reliable data on d values and integrated intensities, an imaging plate (IP) has been applied to high-pressure diffraction experiments with a diamond anvil cell using synchrotron radiation. The IP was found to be more effective than a conventional x-ray film by a factor of 30, and more effective than an energy dispersive method by several times. In order to integrate the intensity data on the IP, a histogram method was successfully developed. This combination proved to give a lattice constant with relative accuracy of 2×10−4, and observed integrated intensities which excellently agree with calculated ones.
