Abstract: Systems and methods are described for a compact x-ray system that uses optical energy for triggering x-ray generation rather than a traditional filament. A photocathode is illuminated and the ensuing electrons are directed to an anode resulting in x-ray generation, resulting in increased x-ray source durability. Pulsing, beam forming, scanning, varying x-ray characteristics, longevity of source and other desirable attributes not currently available in the state of the art are achievable, through the use of shaped, multi-materialed photocathodes, shaped, multi-materialed anodes, arrays of optical lines, and so forth, as some examples. Inexpensive, highly controllable sources such as solid-state lasers can be used, permitting a wide variety of applications and power levels.
