The optical fiber 1224, the laser 1221 and the image collector 1222 are all arranged on the outside of the shielding structure 1100. One end of the incident optical fiber 1223 is connected to the laser emission port of the laser 1221, and the other end passes through the shielding structure 1100 and faces the carrying surface 1211 to irradiate the laser beam to the sample to be tested. One end of the output optical fiber 1224 is connected to the image collector 1222, and the other end passes through the shielding structure 1100 and faces the carrying surface 1211 to transmit the laser beam reflected by the sample to be tested to the image collector 1222. The analyzer 1230 is arranged on the outside of the shielding structure 1100 and is communicatively connected with the host 1220.

[0057] In the Raman spectroscopy analysis system 1000 of the present embodiment, a sample to be tested is carried on a carrying surface 1211 of a carrying platform 1210, a laser 1221 emits a laser beam, and the laser beam is transmitted through an incident optical fiber 1223 to irradiate a test area of ​​the sample to be tested, and is reflected by the sample to be tested. Part of the laser reflected by the sample to be tested is transmitted to an image collector 1222 through an outgoing optical fiber 1224, and an analyzer 1230 reads the laser signal received by the image collector 1222 and performs Raman spectroscopy analysis on it, so that the staff can grasp the micro-region composition of the test area of ​​the sample to be tested. In this process, since the Raman spectroscopy analysis system 1000 is provided with a shielding structure 1100, the carrying platform 1210 is arranged in a shielding cavity 1100 of the shielding structure 1100. 111, the laser 1221, the image collector 1222 and the analyzer 1230 are arranged on the outside of the shielding structure 1100. Therefore, when detecting radioactive samples to be tested, the shielding effect of the shielding structure 1100 can be used to isolate the samples to be tested on the carrying surface 1211 from the equipment and personnel outside the shielding structure 1100, so as to prevent the radiation generated by the samples to be tested from diffusing to the laser 1221, the image collector 1222, the analyzer 1230 and the staff, thereby preventing the radiation from damaging the internal components of the laser 1221, the image collector 1222 and the analyzer 1230, and causing harm to the body of the staff, thereby improving the service life of the Raman spectroscopy analysis system 1000 and achieving safe detection of radioactive substances. In summary, the Raman spectroscopy analysis system 1000 in this embodiment, with the carrier platform 1210 disposed in the shielding cavity 1111 of the shielding structure 1100, and the laser 1221, image collector 1222 and analyzer 1230 disposed outside the shielding structure 1100, can detect radioactive substances in a relatively safe environment.
