Embodiment Construction

[0030] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0031] Such as figure 1 As shown, a high temporal and spatial resolution optical system suitable for X-ray diagnosis mainly includes a detection light generation module, an X-ray response module, an imaging module and a framing recording module. Among them, the probe light generation module can convert the incident short pulse laser into a supercontinuum chirped pulse, and generate two beams of probe light separated in time and with different wavelengths. The polarization directions of the two probe beams are horizontal direction and vertical direction respectively. . The X-ray response module can make each beam of detection light injected from the detection light generation module carry the information of the spatio-temporal evolution process of the X-ray on the target. The imaging module can spatially divide the two beams of detection light emitted by the...

Abstract

The invention discloses a high-temporal-spatial-resolution optical system suitable for X-ray diagnosis. The high-temporal-spatial-resolution optical system comprises a detection light generation module, an X-ray response module, an imaging module and a framing recording module. By adopting the technical scheme, the super-continuum spectrum is taken as the detection light, the detection light generation module selectively outputs the detection light, then the transmission grating is utilized to carry out space light splitting, finally high-performance CCD imaging is adopted, framing is realized by utilizing an optical method, and the device has the advantages of strong anti-interference capability, high time and space resolution and the like; moreover, the recorded time window is adjustable, the time resolution is adjustable, and the spatial resolution is high; meanwhile, the system is extremely compact in structure, can be used for measuring the X-ray spatio-temporal evolution process under the conditions of extremely small space and extremely short time scale, and serves the research of the high-energy density related physical process; in addition, the system can also be used as an active measurement device for material fluorescence property measurement, device structure measurement and the like.

Description

technical field [0001] The invention relates to the technical field of ultrafast process detection, in particular to a high time-space resolution optical system suitable for X-ray diagnosis. Background technique [0002] In laser fusion and high energy density physics research, X-ray space-time diagnosis is a very important technical means. The important properties of the plasma can be obtained by measuring the X-ray energy spectrum and the X-ray space-time evolution process, including important physical parameters such as electron temperature, electron density, and temperature gradient. Therefore, the spatiotemporal evolution of X-rays has become the key data for understanding the interaction between laser and matter, plasma heating and compression, implosion dynamics and even combustion of the target capsule. [0003] The two-dimensional images of the X-ray emission area at different times are the basis for understanding and studying the plasma state and its dynamics of t...
