Abstract

In a tunable Fabry-Perot interferometer, the supports for two parallel mirrors consist of bundles of optical fibers with the mirrors being provided on the ends of the fibers. This structure may be used advantageously in an X-ray display device wherein the structure is located between the display screen on which the visible X-ray image is displayed and a television camera tube. By using the Fabry-Perot interferometer as a light attenuator in such a device, problems where the camera tube is overridden when making an X-ray record can be prevented by causing the reflection coefficient of the mirrors in the visible range of the spectrum to be 99% or more. Also, the half width of the transmission wavelength pass-band of the Fabry-Perot interferometer can be made less than 50 nm.
