The invention provides a multiple-energy-point spectrum resolution soft-X-
ray framing imaging
system. The imaging
system mainly comprises a pin hole array plate, glancing incidence plane mirrors, an optical adjusting mechanism, a filter disc, a light limiting slit, a recording medium and the like. The glancing incidence plane mirrors and the filter disc form an X-
ray enable element, each glancing incidence
plane mirror and one row of pin holes form an imaging channel, the
diameter of each row of pin holes is subjected to optimum design according to observation energy points so as to obtain optimum spatial resolution, and an imaging result is recorded by finally utilizing a time-resolved framing camera or a time-integrated X-
ray imaging plate and the like. The imaging
system is mainly used for observing
laser fusion, Z-hoop condensation
polymerization or a high-temperature high-density
plasma in a laboratory astrophysical experiment and can obtain
plasma evolution images having
time resolution, two-dimensional
space resolution and spectrum resolution through one-time experiment. Compared with the prior art, the multiple-energy-point spectrum resolution soft-X-ray framing imaging system has the advantages of being low in implementation difficulty, wide in application range, flexible in energy area configuration and good in
imaging signal to
noise ratio and having a multiple-energy-point imaging characteristic and the like.
