[0031] See figure 1 , figure 1 A schematic flowchart of the fluorescence imaging method provided by the embodiment of the present application is shown. The application provides a fluorescence imaging method, the fluorescence imaging method comprising:

[0032] Step S110: strike multiple laser beams generated by the laser device on multiple pump material sheets to generate multiple pump X-rays, each of the multiple laser beams and each of the multiple pump material sheets There is a one-to-one correspondence with one pump material sheet.

[0033] Among them, what needs to be explained is that, using the characteristics of isotropy of fluorescence emission, abandoning the traditional concept of using a single or multiple laser beams to superimpose to generate a pump source, the multiple pump laser beams are dispersed, and each laser beam generates its own An independent pump source. Each laser beam is in one-to-one correspondence with each pump material sheet, and in this wa...

Abstract

The invention provides a fluorescence imaging method and device and aims at solving the problem of weak fluorescence signal intensity in a fluorescence imaging technology based on a large intense laser device in the prior art. The fluorescence imaging method comprises steps as follows: multiple beams of laser produced by a laser device are struck on multiple pumping material sheets, multiple pumping X-rays are produced, and the multiple beams of laser are in one-to-one correspondence with the multiple pumping material sheets; the multiple pumping X-rays uniformly irradiate a sample doped withfluorescent elements, fluorescence signals are produced, and the sample doped with fluorescent elements is arranged in the center corresponding to the multiple pumping material sheets; a fluorescenceimage is obtained according to the fluorescence signals emitted by the sample doped with the fluorescent elements.

Description

technical field [0001] The present application relates to the technical field of fluorescence imaging, and relates to a fluorescence imaging method and device. Background technique [0002] At present, it is the most widely used means in the world to use large-scale powerful laser devices to carry out corresponding R&D and research in the industry. Among them, X-ray backlight photography is the most mature technology, and X-rays are also called X-rays. The flow of particles produced by the transition between two energy levels with greatly different energies is an electromagnetic wave with a wavelength between ultraviolet rays and gamma rays. [0003] X-ray fluorescence imaging uses laser targeting to generate hard X-rays as a pump source to excite the fluorescent signal of the tracer elements in the sample to be studied, and obtains the spatial position of the tracer elements through X-ray fluorescence imaging, thereby inferring the position of the sample under loading condi...
