A diversity of instruments have been utilized or proposed for use in X-ray astronomy. This in part reflects the fact that the field is very new, that many competing techniques have been devised for any given type of observation and that there has been a progression to increasingly sophisticated instruments. But most of this diversity is real and simply reflects the very broad range of observations that can be performed and the different kinds of observational opportunities that are presented to the several experimental groups. Useful measurements are being performed over three decades of energy extending from 0.25 keV to 500 keV, positional measurements extend from degrees to arc seconds precision, attempts have been made to measure the polarization of the X-ray sources, time variations are being studied and spectra are being measured to resolutions of the order of ∼20%. The required instruments are being flown on sounding rockets, balloons and satellites. In addition, observation of the diffuse X-ray backgrounds requires even different instruments.
