Abstract: A thermal imaging device is provided for converting an image in the terahertz radiation range to the visible range. In one embodiment, the device includes a converter having a thermochromic liquid crystal layer mounted on a sapphire base. In another embodiment, the device includes a thermal absorption layer including a metal selected from the group of iron, aluminum, tin, and copper. In a further embodiment, the device has an light source shaped as an annulus for illuminating a rearward surface of the converter, configured to permit visible light rays to pass through the annulus for capture by a digital detector. In a final embodiment, the device has a thermal adjustment device for adjusting the temperature of the thermochromic liquid crystal layer to an optimal temperature.

Abstract: An apparatus for producing x-rays for use in imaging applications having a piezoelectric or pyroelectric crystal with an upper surface and a conducting film coating the upper surface. The crystal includes a plurality of field emitters formed as micrometer-scale exposed regions in the crystal having a one or more sharp peaks or ridges, or parallel trenches forming a wedge shaped emitter. The crystal is alternately heated and cooled over a period of time so that spontaneous charge polarization occurs in the crystal. The spontaneous charge polarization causes a perpendicular electric field to arise on the crystal's top and bottom faces, that is enhanced by the sharp peaks or ridges, thereby causing field emission of surface electrons from that location. X-rays are produced when the emitted electrons strike a target material located adjacent to the emitting face, and the X-rays may be filtered or collimated.
Abstract translation: 一种用于制造具有上表面的压电或热电晶体的成像应用的X射线装置和涂覆上表面的导电膜。 该晶体包括在具有一个或多个尖锐峰或脊的晶体中形成为微米级暴露区域的多个场发射体或形成楔形发射极的平行沟槽。 晶体在一段时间内交替加热和冷却，从而在晶体中发生自发电荷极化。 自发电荷极化导致在晶体的顶部和底部面上产生垂直的电场，这被尖锐的峰或脊增强，从而导致来自该位置的表面电子的场发射。 当发射的电子撞击位于发射面附近的目标材料时产生X射线，并且X射线可以被过滤或准直。

Abstract: In an electron accelerator, a conductive housing defines a cavity. Photoelectrons are emitted from a photocathode into the cavity when light is applied to the photocathode. Via an opening formed in a wall of the conductive housing, the photoelectrons are output to the outside of the cavity. Coolant is flowed through a flow path formed in the wall of the conductive housing, to suppress a temperature rise of the conductive housing. The wall of the conductive housing is made by a metal additive manufacturing technique in such a way as to produce a flow path that has a gentle trajectory without discontinuities in gradient.

Abstract: A resonant laser powered micro accelerator platform capable of producing relativistic or near relativistic electrons and, optionally, x-rays. The apparatus has a pair of parallel slab-symmetric dielectric slabs that are separated by a narrow vacuum gap that is preferably tapered. The slabs have a top surface with reflective layers with many periodic slots creating longitudinal periodicity in the structure fields when laser light is directed on the reflectors in one embodiment. Electrons introduced into the gap are accelerated along the length of the slabs. The reflective surface of the slabs is preferably a laminate of alternating layers of high index and low index of refraction materials.
