Abstract: An apparatus comprising a variable aperture for controlling electromagnetic radiation and related systems and methods are described. In one aspect, a variable aperture to control electromagnetic radiation comprises a first substrate, a second substrate, an attenuation fluid, at least one charging electrode, and at least one displacing electrode. The second substrate is located opposite the first substrate and spaced apart from the first substrate to form a gap between the first substrate and the second substrate. The attenuation fluid is located in the gap and configured to absorb electromagnetic radiation of a predetermined wavelength. The at least one charging electrode is in electrical contact with the attentional fluid. The at least one displacing electrode is located on a surface of the first substrate facing the gap or on a surface of the second substrate facing the gap.

Abstract: A radiation imaging device having a moisture impermeable metal layer compressed against a scintillator layer by compressible layer that is mechanically compressed against the scintillator layer. The metal layer is attached to the scintillator substrate by an adhesive ring surrounding the perimeter of the scintillator substrate. The adhesive can further include moisture getter particles. Preferably the metal layer is comprised of aluminum with a thickness between 25 ?m and 100 ?m to allow the layer to be flexible as free of pinholes to prevent ingress of moisture. The compressible layer can be compressed by the housing to maintain the metal layer in contact with the scintillator layer. The metal layer not only provides moisture protection for the scintillator but also increases the output of the scintillator by reflecting photons generated by the scintillator layer toward the photodetector array of the radiation imaging device.
